20 Ft Wide Carport: Lengths Sellers Offer, Fit and Prices

CarportBay Editorial Team Last verified

A 20 ft wide carport holds two vehicles side by side, leaving about 26 to 32 inches per door gap for pickups and sedans. Sellers list it in lengths of 21 to 41 ft, not 20, because the longest full-size pickups run past 20 ft. Metal Carport Depot lists regular-roof prices of $1,895 to $3,045, installed.

What a 20 ft wide carport holds

A 20 ft wide carport holds two vehicles side by side, and the width of those vehicles decides the room left for doors. Metal Carport Depot states that its 20 ft width fits two vehicles side by side. The door gap is the equal space beside the left vehicle, between the pair and beside the right vehicle: (240 in minus the two widths) divided by 3.

Two 2025 Toyota Camrys leave 31.7 in per space, two 2025 Honda CR-Vs 31.0 in, two 2026 Ford F-150s 26.7 in and two 2025 Chevrolet Silverado 1500 crew cabs 25.9 in. Each 2 ft of added width adds 8 in per space. Every width and size is laid out side by side on the carport sizes and widths page. For a pair of vehicles at several widths, see two-car carport dimensions.

Widths exclude mirrors. Parked vehicles are rarely centered, so read each figure as about that many inches.

Lengths sellers offer, and what fits in each

Sellers list a 20 ft wide carport in lengths of 21 to 41 ft, and Table 2 shows the depth each length leaves for four vehicles, as read on October 6, 2026. Metal Carport Depot lists 21, 26, 31 and 36 ft, and Carport Direct lists the same four plus 41 ft.

Why sellers list 21 ft, not 20

A 2026 Ford F-150 in its longest body is 243.9 in long, 3.9 in more than the 240 in of a 20 ft length. A 2025 Chevrolet Silverado 1500 crew cab at 241.4 in runs 1.4 in over. At 21 ft the F-150 clears by 8.1 in and the Silverado by 10.6 in. That margin is body length, not room to swing a door.

The shorter F-150 body, 209.4 in, leaves 30.6 in at 20 ft, so the body style matters as much as the model name. Metal Carport Depot states that no 20x20 model is offered on its page, while Keen's Buildings, Direct Metal Structures and Alan's Factory Outlet list one.

Sedan and SUV in 21 to 36 ft

A 2025 Toyota Camry, 193.5 in long, leaves 58.5 in of depth at 21 ft and 238.5 in at 36 ft. A 2025 Honda CR-V, 184.8 in long, leaves 67.2 in and 247.2 in. Past 21 ft, the added length gives these two vehicles room beyond parking depth. The same two-vehicle arithmetic at 18 ft wide is on the 18x21 carport footprint page.

What each length costs

Metal Carport Depot lists regular-roof 20 ft wide carports from $1,895 at 21 ft to $3,045 at 36 ft, installed, as read on October 6, 2026. Table 4 holds the ladder with the price per square foot and the step between lengths.

Price per square foot

Price per square foot falls from $4.51 at 21 ft to $4.23 at 36 ft, so the longer lengths cost less per square foot. Headline prices from other sellers cover different specs, and Table 5 lists them with the spec each seller states.

The $1,895 in a Metal Carport Depot search-result title is the 20x21 row, not a 20x20. Carport Central shows $10,046 for a 20x21x9 vertical-roof unit that it also titles 20'x20' double carport, which is $23.92 per sq ft over 420 sq ft.

Cost of each added 100 sq ft

In the Metal Carport Depot regular-roof ladder, each added 100 sq ft costs $400 from 21 to 26 ft, $350 from 26 to 31 ft and $400 from 31 to 36 ft. That is $4.00, $3.50 and $4.00 for each added square foot.

What leg height, roof style and gauge change

Leg height, roof style and gauge change the price of a 20 ft wide carport more than footprint does. Rows for 20x20 and 20x21 footprints seen on October 6, 2026 run from $1,799.10 to $10,046, which is 5.6 times apart.

Leg height

Metal Carport Depot's ladder rows have 6 ft legs. Keen's Buildings lists 6 ft legs as standard on its 20x20, with options up to 20 ft. Carport Central's 20x20 starting price is for a 7 ft leg, and Direct Metal Structures' $1,910 is for a 9 ft eave. Compare rows only at the same height.

Regular, A-frame and vertical roofs

Metal Carport Depot's vertical-roof rows run $3,745 at 31 ft and $4,195 at 36 ft, which is $1,100 (41.6%) and $1,150 (37.8%) above its regular-roof rows at the same lengths. Keen's lists its 20x20 as an A-frame. Carport Direct lists A-frame and vertical roofs for 21 to 36 ft and vertical only at 41 ft.

Frame and panel gauge

Keen's lists 12 or 14 gauge frames. Carport Central lists a 14 gauge frame with a 12 gauge upgrade. Metal Carport Depot's 20x31x6 regular carport has a 14 gauge frame and 29 gauge panels. A lower gauge number means thicker steel.

Does a 20 ft wide carport need a permit?

A 20 ft wide carport of any listed length is over the 200 sq ft line in section R105.2 of the 2021 International Residential Code. That section exempts one-story detached accessory structures of 200 sq ft or less, as printed in the Grant County, Washington copy. At 20 ft by 21 ft the carport covers 420 sq ft, 2.1 times the line, and at 20 ft by 36 ft it covers 720 sq ft, 3.6 times. Confirm current requirements with your local building department before beginning construction.

Wind and snow options sellers list

Sellers state wind and snow ratings for 20 ft wide carports as options, and none of the pages read on October 6, 2026 names a code edition for them.
