How to Choose the Right Enclosed Trailer Size: A Complete Buyer’s Guide for Work, Business, Equipment, and Recreation
Choosing the right enclosed trailer size is one of the most important decisions a buyer can make. The right trailer protects tools, equipment, vehicles, inventory, and personal cargo while making hauling easier, safer, and more organized. The wrong trailer can create daily frustration: not enough room, too much weight, poor load balance, limited door access, difficult towing, or a setup that no longer works as the buyer’s business grows.
For many buyers, the first question is simple: what size enclosed trailer do I need? The answer depends on much more than the outside dimensions printed on the trailer listing. A smart buyer should consider cargo type, equipment weight, interior space, towing capacity, axle setup, ramp door vs. barn doors, interior height, tie-down needs, shelving, ventilation, and whether the trailer will be used for personal hauling, a small business, a trade, landscaping, motorcycles, ATVs, UTVs, car hauling, mobile service work, or long-term storage.
Make My Trailer, a factory-direct enclosed trailer company based in Douglas, Georgia, helps buyers compare enclosed cargo trailer sizes, custom options, stock trailer availability, axle setups, door styles, and factory-direct pickup options. This guide explains how common enclosed trailer sizes compare, what each size is best for, and what buyers should ask before requesting a quote or reserving a trailer.

Why Enclosed Trailer Size Matters
An enclosed trailer is not just a box on wheels. It is a mobile storage room, equipment hauler, business asset, tool vault, moving trailer, powersports carrier, or vehicle transport solution. Size affects almost everything:
A trailer that is too small may save money upfront but cost more later if the buyer quickly outgrows it. A trailer that is too large may provide plenty of space but require a stronger tow vehicle, more parking room, higher tire/brake maintenance, and more careful maneuvering. The best enclosed trailer size is the one that fits the buyer’s real cargo, towing setup, storage needs, and future plans.
Quick Enclosed Trailer Size Comparison
| Enclosed Trailer Size | Best For | Common Buyer Profile |
|---|---|---|
| 5x8 enclosed trailer | Small cargo, tools, light equipment, personal hauling | Homeowners, hobby users, light-duty buyers |
| 6x10 enclosed trailer | Tools, small business equipment, motorcycles, light landscaping | First-time buyers, small contractors, weekend users |
| 6x12 enclosed trailer | Versatile work trailer, mobile business setup, motorcycles, lawn equipment | Contractors, landscapers, detailing businesses, recreational users |
| 7x14 enclosed trailer | Larger tools, side-by-side hauling, organized work setups, growing businesses | Contractors, lawn care companies, small business owners |
| 8.5x16 enclosed trailer | Wider cargo, multiple machines, contractor storage, event equipment | Construction crews, mobile service businesses, serious equipment haulers |
| 8.5x20 enclosed trailer | Larger business setups, car hauling, motorcycles, inventory, mobile workspaces | Automotive users, contractors, commercial buyers |
| 8.5x24 enclosed trailer | Maximum storage, vehicle transport, race teams, advanced custom builds | Car haulers, race teams, mobile businesses, high-capacity buyers |
These sizes are common reference points, but the correct choice depends on the exact trailer configuration. A 6x12 with extra height, E-track, a ramp door, and interior lighting may serve a business better than a larger basic trailer with no organization. An 8.5x20 may be ideal for car hauling, but only if it is built with the right axle capacity, ramp setup, tie-down system, and frame strength.
Start With What the Trailer Must Carry
Before choosing a trailer size, list the cargo that will be hauled most often. This should include the actual equipment, tools, machines, inventory, or vehicles—not just a general category.
For example, a landscaper should not simply say “lawn equipment.” The buyer should list the mower width, number of mowers, trimmers, blowers, fuel cans, toolboxes, spare parts, and storage racks. A mobile detailer should list the water tank size, generator, pressure washer, hose reels, chemical storage, shelving, ventilation, and electrical needs. A motorcycle owner should measure the length and handlebar width of each bike and consider wheel chocks, tie-down angles, helmets, gear bags, and walk-around room.
The buyer should also think about how often cargo will be loaded and unloaded. A trailer used daily for work needs a more practical interior layout than a trailer used occasionally for weekend hauling.
Understand Interior Dimensions, Not Just Exterior Size
Trailer names such as 6x12 or 7x14 usually refer to approximate box size, but buyers should confirm the actual usable interior dimensions before ordering. Important measurements include:
The smartest approach is to measure the largest item being hauled, then add extra room for tie-downs, ramps, walking space, and future equipment.
5x8 Enclosed Trailer: Best for Light Hauling and Personal Cargo
A 5x8 enclosed trailer is a compact, easy-to-tow option for buyers who need secure cargo space without stepping into a larger work trailer. This size is often a good fit for homeowners, hobby users, light-duty buyers, and people who need a small enclosed trailer for occasional hauling.
A 5x8 can work well for:
The main advantage of a 5x8 is convenience. It is easier to store, easier to maneuver, and usually less demanding on the tow vehicle than larger enclosed trailers. For buyers with limited parking space or lighter hauling needs, it can be a practical first trailer.
The limitation is growth. A 5x8 can fill up quickly once a buyer adds shelving, toolboxes, fuel cans, bins, or bulky equipment. It may not be the best choice for a growing business, lawn care operation, mobile detailing setup, or buyer who expects to add more cargo soon.
6x10 Enclosed Trailer: A Practical Step Up
A 6x10 enclosed trailer gives buyers more width and length than a 5x8 while still remaining manageable for many first-time trailer owners. It is often a strong option for small contractors, light landscaping, motorcycle hauling, weekend users, and small business equipment.
A 6x10 can work well for:
A 6x10 is often easier to tow than longer trailers but offers noticeably more usable room than a 5x8. Buyers who feel a 5x8 is too tight but do not need a full 6x12 may find the 6x10 to be a balanced choice.
The key question is whether the buyer needs only floor space or organized storage. Once shelves, wall hooks, tie-downs, or cabinets are installed, usable walking and loading room changes. Buyers planning to organize tools along the walls should consider whether stepping up to a 6x12 or 7x14 would make daily use easier.
6x12 Enclosed Trailer: One of the Most Versatile Sizes
A 6x12 enclosed trailer is one of the most popular and versatile sizes because it works for many different buyers. It is large enough for serious hauling but still compact enough for many small businesses, contractors, landscapers, motorcycle owners, and recreational users.
A 6x12 can work well for:
For many first-time business buyers, a 6x12 is the first size that feels like a true work trailer. It can hold tools, supplies, small machines, and storage systems while remaining easier to maneuver than larger trailers.
A 6x12 can be configured with a ramp door for rolling equipment, barn doors for dock-style access, E-track for cargo control, shelving for tools, insulation for temperature control, and vents for airflow. Depending on the payload requirements, buyers may compare single axle and tandem axle 6x12 setups.
6x12 vs. 7x14 Enclosed Trailer: Which One Makes More Sense?
The comparison between a 6x12 enclosed trailer and a 7x14 enclosed trailer is one of the most common decisions buyers face.
A 6x12 enclosed trailer usually makes sense when the buyer wants:
A 7x14 enclosed trailer may be the better choice when the buyer needs:
For small business owners, the decision often comes down to growth. If the trailer only needs to handle current equipment, a 6x12 may be enough. If the business is adding employees, larger machines, more tools, or inventory, a 7x14 can prevent outgrowing the trailer too quickly.
7x14 Enclosed Trailer: More Room for Growing Businesses
A 7x14 enclosed trailer gives buyers more space and flexibility than a 6x12. The extra width and length can make a major difference for contractors, landscapers, mobile service providers, and recreational users who need room for larger equipment or better organization.
A 7x14 can work well for:
A 7x14 is also a strong size for buyers who want wall-mounted storage. Shelving, cabinets, racks, and E-track take up space. The extra width and length can make the trailer easier to work inside without constantly moving cargo around.
Many buyers choose 7x14 when they want a trailer that can grow with their business. It provides more room than a 6x12 but does not feel as large as an 8.5-wide trailer.
8.5x16 Enclosed Trailer: Wider Cargo and Serious Work Capacity
An 8.5x16 enclosed trailer is a strong option for buyers who need extra width, more interior volume, and more room for organized equipment. This size is commonly used by construction crews, mobile service businesses, event companies, serious equipment haulers, and buyers who need more than a small utility-style enclosed trailer.
An 8.5x16 can work well for:
The 8.5-foot width is important. It allows wider cargo and more side-to-side organization. However, buyers must also consider that wider trailers can be more affected by wind, require more awareness when towing, and may need more parking or storage space.
This size is often best for buyers who already know they need more room than a 7x14 and have a tow vehicle capable of handling the loaded trailer safely.
8.5x20 Enclosed Trailer: Large Business Setups and Vehicle Hauling
An 8.5x20 enclosed trailer is a larger enclosed trailer often used for car hauling, business storage, motorsports, equipment transport, mobile workspaces, and larger inventory setups. This size provides enough length for more advanced layouts and is commonly compared by buyers who need a serious enclosed cargo solution.
An 8.5x20 can work well for:
Buyers considering an 8.5x20 should pay close attention to GVWR, axle rating, ramp door capacity, tie-down placement, trailer brakes, tire load rating, and tow vehicle capacity. A larger trailer is not only about space; it must be properly matched to the intended cargo.
For car hauling, the buyer should confirm the trailer is built as a car hauler or appropriately configured for vehicle transport. Interior width, ramp angle, rear door opening height, floor strength, D-rings, and axle capacity all matter.
8.5x24 Enclosed Trailer: Maximum Space and Advanced Custom Builds
An 8.5x24 enclosed trailer is one of the largest common enclosed cargo trailer sizes for buyers who need maximum storage, vehicle transport, multi-purpose business use, or advanced custom configurations.
An 8.5x24 can work well for:
This size gives buyers room for more than cargo. It can support workbenches, cabinets, cabinets plus open floor space, spare tire storage, lighting, electrical packages, insulation, A/C, awnings, and other custom features.
The tradeoff is towing demand. An 8.5x24 requires a capable tow vehicle, proper hitch setup, careful loading, and more space to park and maneuver. Buyers should not choose this size only because they want “the biggest option.” They should choose it because their cargo, business model, or vehicle transport needs justify it.
Single Axle vs. Tandem Axle: What Buyers Should Know
Trailer size is only one part of the decision. Axle setup matters just as much.
A single axle enclosed trailer usually works best for lighter cargo, easier maneuvering, lower maintenance, and buyers who do not need heavy payload capacity. Single axle trailers are common in smaller sizes such as 5x8, 6x10, and many 6x12 configurations.
A tandem axle enclosed trailer usually works better for heavier cargo, longer trailers, more frequent highway towing, better load distribution, and higher GVWR configurations. Tandem axle trailers are common in larger sizes such as 7x14, 8.5x16, 8.5x20, and 8.5x24, though some smaller models may also be available with tandem axles.
Tandem axle trailers generally offer more stability and capacity, but they also include more tires, more bearings, more brakes, and more components to maintain. The right choice depends on cargo weight, tow vehicle capacity, usage frequency, and how often the trailer will be loaded near its maximum rating.
Ramp Door vs. Barn Doors
Door style can make or break the trailer’s daily usefulness.
A ramp door is best when the buyer will roll cargo into the trailer. This includes motorcycles, lawn mowers, ATVs, UTVs, tool carts, pressure washers, generators, and wheeled equipment. A ramp door makes loading easier and safer when cargo has wheels.
Barn doors may be better when the buyer loads boxes, pallets, hand tools, furniture, or cargo by hand. Barn doors are also useful when the trailer is backed near a dock, wall, or tight space where a ramp door may not have enough room to lower.
Buyers should choose based on the loading method, not just appearance. If most cargo rolls in, choose a ramp. If most cargo is carried in by hand or loaded from a dock, barn doors may be more practical.
Interior Height: Standard, Extra Height, and Real-World Comfort
Interior height is often overlooked. A buyer may choose the right length and width but later realize the trailer is uncomfortable to work inside or too low for certain equipment.
Extra height can help with:
However, extra height can also increase wind resistance and total trailer weight. Buyers should choose extra height when it improves real use, not simply because it sounds better.
GVWR, Payload, Empty Weight, and Tow Vehicle Capacity
A buyer should never choose an enclosed trailer based only on floor space. Weight ratings matter.
The buyer should confirm that the tow vehicle, hitch, ball mount, trailer brakes, tires, and cargo weight all work together. A trailer may physically fit the cargo but still be the wrong choice if the loaded weight exceeds the tow vehicle’s capacity or the trailer’s rating.
Load Balance and Cargo Securement
A properly loaded enclosed trailer is easier to tow and safer to control. Heavy cargo should be positioned carefully, side-to-side balance should be considered, and cargo should be secured so it cannot shift during braking, turning, or rough road conditions.
Good cargo control may include:
This is especially important for motorcycles, ATVs, UTVs, mowers, generators, compressors, and tool chests. Cargo that shifts can change tongue weight, affect stability, damage the trailer interior, or create a dangerous towing condition.
Choosing a Trailer Size by Business Type
Landscaping and Lawn Care
Landscapers often compare 6x12, 7x14, 8.5x16, and 8.5x20 enclosed trailers. A smaller operation may use a 6x12 for a push mower, trimmers, blowers, fuel cans, and hand tools. A growing lawn care business may need a 7x14 or 8.5x16 for larger mowers, shelves, racks, and maintenance supplies.
For landscaping, buyers should consider:
Mobile Detailing
Mobile detailing businesses often need room for a water tank, pressure washer, generator, hose reels, chemicals, towels, vacuums, shelving, and ventilation. A 6x12 can work for compact setups, while 7x14 and 8.5x16 trailers offer more space for tanks and organized workflow.
Mobile detailers should consider:
Contractors and Trades
Electricians, plumbers, remodelers, flooring installers, HVAC technicians, roofers, and general contractors often need organized tool storage more than empty floor space. A 7x14, 8.5x16, or 8.5x20 may provide better wall storage, ladder rack options, shelves, bins, and workbench space.
Contractors should consider:
Motorcycle, ATV, and UTV Owners
Motorcycle owners may use 6x10, 6x12, 7x14, or 8.5x16 trailers depending on the number and size of machines. ATV and UTV owners often need to confirm width, height, door opening, ramp angle, and tie-down placement.
Powersports buyers should consider:
Car Hauling and Motorsports
Car haulers often compare 8.5x20 and 8.5x24 enclosed trailers. These buyers should confirm the trailer is properly configured for vehicle transport, not simply “large enough.” Important details include ramp angle, rear door opening, interior width, fender clearance, axle capacity, floor strength, tie-downs, winch options, lighting, and spare tire storage.
Race teams and automotive buyers may also want cabinets, tire racks, workbenches, awnings, electrical packages, and finished interiors.
Common Trailer Size Mistakes to Avoid
Custom Options That Can Change the Best Trailer Size
Sometimes the right size depends on the upgrades a buyer plans to add. A 6x12 with shelving, insulation, and equipment racks may feel smaller than expected. A 7x14 with E-track and cabinets may be more efficient than a larger trailer with no organization.
Popular upgrades include:
Buyers should decide which upgrades are essential before finalizing the size.
Factory-Direct Buying: Why It Helps With Size Selection
A factory-direct enclosed trailer buying process can help buyers compare sizes, configurations, and options before committing. Instead of choosing from whatever happens to be on a local lot, buyers can discuss intended use, compare popular sizes, request custom options, check stock availability, and determine whether a build-to-order or ready-to-go trailer makes more sense.
Make My Trailer supports buyers from its location in Douglas, Georgia, helping customers compare enclosed cargo trailer sizes, custom builds, stock trailer options, axle setups, door styles, and upgrades for work, business, equipment hauling, and recreational needs.
Factory-direct support can be especially useful when buyers are unsure whether they need a 6x12 or 7x14, whether they should choose single axle or tandem axle, whether a ramp or barn door is best, or whether they should plan for growth with a larger size.
Questions to Ask Before Choosing an Enclosed Trailer Size
Before buying, ask these questions:
The buyer who answers these questions clearly is much more likely to choose the right trailer the first time.

Final Takeaway: Choose the Trailer Based on What It Needs to Do
Many buyers begin by asking, “What size enclosed trailer do I need?” A better question is, “What do I need this trailer to do every day?”
A 5x8 may be perfect for light hauling. A 6x10 may be a practical step up for tools, motorcycles, and weekend use. A 6x12 may be the best all-around choice for small businesses, mobile services, landscaping, motorcycles, and general hauling. A 7x14 may be the smarter choice for buyers who need extra room, better organization, or future growth. An 8.5x16, 8.5x20, or 8.5x24 may be necessary for wider cargo, car hauling, mobile workspaces, larger business setups, and advanced custom builds.
The right enclosed trailer size protects cargo, improves organization, supports business growth, and makes hauling more efficient. Buyers should compare the trailer’s dimensions, payload, axle setup, door style, towing requirements, customization options, and long-term use before making a final decision.
Make My Trailer helps buyers compare enclosed cargo trailer sizes, factory-direct options, stock trailer availability, custom builds, axle setups, door styles, and popular upgrades from its location in Douglas, Georgia. Whether the buyer needs a compact enclosed trailer for personal hauling or a larger trailer for work, business, equipment, recreation, or vehicle transport, choosing the right size begins with understanding the cargo, the tow vehicle, and the real-world job the trailer needs to perform.
