Car Interior & Upholstery Calculators
Free, practical tools for planning an interior build — estimate fabric, carpet, and foam for a re-trim, work out the true VLT of a tint, size a boot or load bay, and cost the materials before you order.
Upholstery Fabric Calculator
Sum your panel areas, add a waste allowance, and get the linear metres or yards of fabric or vinyl to buy — or the leather hides a re-trim needs.
Carpet Area Calculator
Add up the footwells, tunnel, and cargo floor as rectangles for the total automotive carpet area, with a trim allowance built in.
Seat Foam Calculator
Turn cushion dimensions into a foam volume in cubic metres and board-feet, and see the finished mass at your chosen density.
Window Tint VLT Calculator
Combine a film's VLT with the glass's own VLT for the real light transmission, and check it against a legal minimum you set.
Cargo Volume Calculator
Estimate a boot or load bay in litres and cubic feet from its dimensions, with a shape factor for wheel wells and curved trim.
Material Cost Estimator
Turn an area, a coverage-per-unit figure, and a unit price into whole units to buy and the total spend — vinyl wrap, adhesive, dye, and more.
