A 22x22 garage floor is 484 square feet, the snug two-car pour. Both cars fit and the doors clear, but there is less slack for shelving and a bench than the 24x24 gives you. It is a real, frequently quoted size, and because it lives under vehicles it prices like a garage, not like a patio.
Example rates, worked out
| Finish | Example rate | 22x22 (484 sq ft) |
|---|---|---|
| Standard broom | $9 / sq ft | $4,356 |
| Colored | $12 / sq ft | $5,808 |
Example rates only. A garage floor usually gets a plain broom finish, so the finish upcharge matters less here than the reinforcement and prep questions below. Your mix cost and market set your real rate.
Price it as a garage pour
Daily wheel loads argue for pouring heavier than 4 inch flatwork and for reinforcing it. Mesh or rebar at the example $1.50 per square foot adds $726 on 484 feet. If you are replacing an old floor, tear-out at $4 per square foot is $1,936, and it belongs on the quote as its own line so the customer sees what the demolition buys.
The load case for going thicker is spelled out in 4 inch vs 6 inch slab. The bigger sibling of this pour, with room to actually store things, is the 24x24 garage slab.
Other sizes, same example rates
The garage floor concrete calculator opens preloaded at 22x22 and reruns for a 24x36 three-car floor or any footprint a customer names. The method behind the number is in how to price a garage floor, and the general flatwork method is in how to price a concrete slab.
