Window Film Estimator

How much Window Film do you need?

For homes and businesses. Add each window size, see square footage and a material base estimate instantly — then send it to us for a reviewed quote if you'd like.

Measure the visible glass in inches — decimals (35.5) or fractions (35 1/2) both work. Several windows the exact same size? Enter one row and set how many.

How to Measure Your Windows

Measure the visible glass only — not the frame, trim or rubber seals.
Measure width and height in 3 spots each (top, middle, bottom for width; left, center, right for height) and use the smallest number for each dimension.
Record each measurement to the nearest 1/8 inch.
Label every window by room so your Window Film pieces are easy to match up.

Every order is reviewed by a real person before any film is cut — if a measurement looks off, we'll contact you before anything ships.
