DTF & Shop Cost
Square Inches to Square Feet Converter
Convert design area between in² and ft² for film and material pricing.
This is the bridge between design size and DTF/vinyl cost calculators.
How it works
Area (in²) = width_in × height_in.Area (ft²) = in² ÷ 144.
Multiply ft² by your film or vinyl $/ft² to get material cost before labour and waste. For nested jobs, use gang-sheet fill to share sheet area across designs.
Worked example
A 10 × 12 in design is 120 in² → 120 ÷ 144 = 0.833 ft². At $1.80/ft² film, material is about $1.50 before waste and ink.Use with

Frequently asked questions
Is this the same as fabric yards?
No — yards need width of the roll. This is pure area conversion.
Why divide by 144?
One square foot is 12 × 12 = 144 square inches.
Do I include bleed in the area?
If you print bleed or a cut margin, include that rectangle — you are buying that film whether the art uses it or not.
Is roll waste included?
Not automatically. Add waste % in your cost calculator or pad $/ft² after you measure scrap.
