1. Measure floor
Measure length and width of the garage in feet. Standard 2-car garage is 20 × 20 ft.
What is garage square footage?
Garage square footage is the total floor area of a garage measured in square feet. A 1-car garage is 240-300 sq ft (22.3-27.9 m²). A 2-car garage is 400-576 sq ft (37.2-53.5 m²). A 3-car garage is 600-900 sq ft.
Getting started
How to Calculate Garage Square Footage
To calculate garage square footage, measure length and width of the garage floor in feet and multiply length × width. A standard 20 × 20 ft (6.1 × 6.1 m) 2-car garage equals 400 sq ft (37.2 m²).
2. Subtract storage
Subtract permanent cabinets and workbench footprint when calculating epoxy coverage.
3. Plan epoxy or coating
Garage epoxy kits typically cover 200-500 sq ft each. Divide garage area by kit coverage.
Quick reference
Reference
1 acre = 43,560 square feet
1 square yard = 9 square feet
1 square meter = 10.764 square feet
1 square inch = 0.00064516 square feet
Material pricing
Calculate Cost of Materials
Garage floor epoxy costs $3-12 per sq ft DIY or $5-15 installed. Multiply garage area by price per unit for total coating cost.
There are 2 steps to calculate material cost:
- Enter the price per kit and the coverage in square feet listed on the kit label.
- The Square Foot Calculator divides garage area by kit coverage and multiplies by kit price.
A 400 sq ft garage needs 1-2 epoxy kits. Add primer, etching solution, and tools to the budget. Buy slightly extra to ensure full coverage.
