Square Inches to Square Feet Converter

Convert design area between in² and ft² for film and material pricing.

New here? Jump to how it works · FAQ

Film, vinyl and some substrate pricing is quoted per square foot while artwork lives in inches. Convert width × height into square inches, then into square feet, so material cost lines up with how you buy rolls and sheets.

This is the bridge between design size and DTF/vinyl cost calculators.
Convert design square inches to square feet for film pricing.

How it works / formula

Calculation steps

  1. Area (in²) = width_in × height_in.
  2. Area (ft²) = in² ÷ 144.
  3. 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

Example (illustrative)

  • 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.

Assumptions & limitations

This calculator provides an estimate for planning and quoting. Actual results vary with supplier pricing, ink coverage, waste, labour rates, equipment and marketplace fee changes. Always verify critical numbers before production. See the disclaimer.

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.
