20x20 Carport and Metal Garage: Sizes, Prices and Options

A 20x20 is the most searched size for a reason: 400 square feet is the classic footprint for two small cars or one vehicle plus storage, and it fits on most residential lots. Below are the real prices of the 20x20 metal garage we install and the closest carport in our catalog, so you can see what you get for each budget.

20x20 prices

Starting prices listed on our site in fall 2026, with delivery and installation included. They are estimates: they vary by location, exclude sales tax and can change, so confirm with a quote for your address.

• 20' x 20' x 10' metal garage: from $9,960. Horizontal walls, a wide 16' x 8' roll-up door, two 24" x 36" windows and a walk-in door. View model
• 24' x 20' x 7' carport: from $4,310. The closest open carport we list: 3' panels on both sides and one gable end closed. View model

There is no exact 20x20 carport in the catalog because every building is built to order. A 20x20 carport can be quoted at that exact size; the 24x20 above gives you a real reference for the price range of an open structure of this footprint.

What fits in a 20x20

• Two compact cars, parked close, with the 16-foot door of the garage making it easy to pull both in.
• One car or pickup plus storage: bikes, a mower, shelving and a small bench along the back wall.
• A small shop for tools and projects, especially with the two windows for daylight.

Two full-size pickups are tight in 20 feet of width. If that is your plan, look at 22 to 24 feet wide; our 2 car garage size guide shows the dimensions that work. If you need more length, the 20x30 carport and garage guide adds 10 feet for about the same width.

Carport or garage at 20x20?

The open carport costs less than half of the enclosed garage. It covers vehicles from snow, sun and hail and can be enclosed later. The garage adds walls, a lockable roll-up door, a walk-in door and windows, which makes it usable as a shop or storage room year-round.

Options that change the price

• Height (taller legs for a lift or a taller vehicle).
• Roof style: Regular, A-Frame Horizontal or A-Frame Vertical.
• Doors and windows, each priced separately.
• 12-gauge framing instead of the standard 14-gauge, and 26-gauge panels instead of 29-gauge.
• Insulation, from R-6 to R-30 depending on the package.

Every building is engineer-certified for your county's snow and wind loads, and anchors are available for concrete, asphalt or ground. Delivery and installation are included, with a lead time of 2 to 5 weeks (weather permitting).
