Window tint square footage calculator for flat-glass jobs
Square footage is the foundation of flat-glass tint pricing. TintLog helps shops turn pane measurements into square footage totals faster, then apply saved film pricing without manual calculator work.

Square feet = width in inches x height in inches / 144
If a pane measures 36 in x 60 in:
36 x 60 = 2,160 square inches
2,160 / 144 = 15 square feet
If there are 8 panes, total square footage is 120 square feet.
Why square footage mistakes matter
- Bad math changes the quote before you even discuss film options.
- Repeated panes multiply small mistakes into larger pricing gaps.
- Manual calculator cleanup slows down follow-up when the job should already be moving.
Why shops use a square footage calculator
Most flat-glass tint shops either price directly by the square foot or use square footage as the core measurement behind pricing decisions. That makes a square footage calculator one of the most important parts of the quoting workflow.
TintLog helps with that math first, then carries the job forward into quote, estimate, and invoice steps.
A simple workflow for square footage pricing
Capture pane width and height in inches.
Divide square inches by 144 to get square feet.
Multiply by quantity for repeated panes or room groups.
Apply your film rate to get a quote-ready total.
Commercial example
24 panes at 42 in x 66 in each:
42 x 66 = 2,772 square inches
2,772 / 144 = 19.25 square feet per pane
19.25 x 24 = 462 square feet total
Residential example
10 panes at 30 in x 54 in each:
30 x 54 = 1,620 square inches
1,620 / 144 = 11.25 square feet per pane
11.25 x 10 = 112.5 square feet total
