If you're shopping for a steel carport in Middle Tennessee, one of the first questions you'll run into is: what size do I actually need? A carport that's too small won't protect your truck, RV, or boat the way you want, and going too big means paying for space you don't use.
Let's walk through the measurements that matter, what fits what, and a few things folks around Waverly and Middle Tennessee often overlook when they're sizing up a carport.
Why Size Matters More Than You Think
A carport isn't just about keeping rain off your vehicle. You want enough clearance to open doors, walk around comfortably, and maybe store a toolbox or two. You also want to think about future needs—if you're buying a carport for your current truck but plan to upgrade to a dually or a bigger RV down the road, it pays to plan ahead now.
Steel carports are built to last, and they're available in a range of standard sizes. The good news? Most can be customized in width, length, and height to fit exactly what you need.
Standard Carport Sizes and What Fits
Here's a quick reference for common carport sizes and what they'll comfortably cover:
| Carport Size | What It Fits |
|---|---|
| 12' x 20' | Compact car, small truck, or motorcycle |
| 12' x 30' | Full-size pickup truck or SUV |
| 18' x 20' | Truck with extra side clearance, or two small vehicles |
| 20' x 30' | Large truck, small RV, or boat on trailer |
| 24' x 30' or larger | Class A or Class C RV, large boat, or multiple vehicles |
These are starting points. Your actual needs depend on your vehicle's dimensions and how much breathing room you want.
Sizing a Carport for Your Truck
Most full-size pickup trucks—like a Ford F-150, Chevy Silverado, or Ram 1500—are around 6 to 7 feet wide and 19 to 20 feet long (not counting the bed). A 12' x 30' carport will cover a standard truck just fine, but if you've got a dually, a lifted truck, or you want room to walk around and keep gear on the sides, consider bumping up to an 18' or 20' width.
Height matters, too. Standard carport legs are usually 6 to 7 feet, but if your truck has a lift kit, a toolbox, or a ladder rack, go with at least 8 or 9 feet of clearance. You don't want to be ducking or scraping every time you pull in.
Extra Length for Tailgates and Hitches
Don't forget to account for anything sticking out past your bumper—trailer hitches, bike racks, or tool carriers. Add a few extra feet of length if you keep accessories mounted year-round.

Sizing a Carport for Your RV
RVs vary a lot, so it's important to measure yours (or the one you're planning to buy) before you order a carport. Here's a rough breakdown by RV type:
- Class B (camper van): Usually 7–8' wide, 17–21' long, 9–10' tall. A 12' x 25' carport with 10' legs works for most.
- Class C (cab-over motorhome): Around 8' wide, 21–31' long, 10–12' tall. Consider a 14' x 35' carport with 12' legs.
- Class A (bus-style motorhome): 8–9' wide, 26–45' long, 11–13' tall. You'll want at least a 14' x 40' or larger, with 12–14' legs.
- Travel trailers and fifth wheels: Measure the entire rig including the tongue or hitch. A 14' x 35' or 14' x 40' is common.
Height is critical with RVs. Measure from the ground to the tallest point—usually the AC unit or a vent on the roof—and add at least a foot of clearance for safety and airflow.
Sizing a Carport for Your Boat
Boats on trailers need enough length to cover both the hull and the trailer tongue, plus a little extra. Most single-axle boat trailers with 16- to 20-foot boats fit under a 14' x 30' or 14' x 35' carport. Larger boats—especially those with tall fishing towers, T-tops, or bimini tops—need extra height and width.
Here's what to measure:
- Total length from the trailer hitch to the back of the motor or swim platform
- Width at the widest point (usually the beam of the boat)
- Height from the ground to the tallest point (tower, antenna, etc.)
If you've got a pontoon or a bass boat with a raised deck, don't guess—measure it. A 14' or 18' wide carport gives you room to walk around and work on the boat without feeling cramped.
A Few Extra Things to Think About
Beyond the vehicle itself, here are a few details that can help you get the right size:
- Side clearance: Plan for at least 2 feet on each side so you can open doors, step out comfortably, and move around.
- Future vehicles: If you're thinking about upgrading your truck or buying a bigger RV in a few years, it's easier to go a little bigger now than to replace the whole carport later.
- Extra storage: Some folks like to keep a mower, toolbox, or kayak under the same roof. Adding 4 to 6 feet of width or length can give you that flexibility.
- Local codes: Most areas around Waverly and Middle Tennessee don't require permits for carports, but it's worth checking with your county if you're not sure.

Frequently Asked Questions
What's the most common carport size for a full-size truck?
A 12' x 30' carport is the most popular size for a standard full-size pickup. If you have a dually, a lift, or want extra room, an 18' x 30' or 20' x 30' is a better fit.
Do I need a building permit for a carport in Middle Tennessee?
Requirements vary by county. Most areas around Waverly don't require a permit for a carport, but it's smart to check with your local building department before you order.
Can I add sides or enclose my carport later?
Yes. Many customers start with an open carport and add sides, gables, or full enclosures down the road. Steel carports are easy to customize as your needs change.
How tall should my carport be for an RV with a rooftop AC unit?
Measure from the ground to the top of the AC unit and add at least 12 inches of clearance. For most Class C and Class A RVs, that means 12' to 14' legs.
