Fabric Calculator
Measurement Type: Choose inches or centimetres — all fields will update to match.
Width of Uncut Fabric: The full width of your fabric bolt as purchased, before any cutting. Common widths are 44" (quilting cotton) or 60" (apparel fabric).
Margins / Seam Allowance: The extra fabric added around each pattern piece for sewing. A typical seam allowance is ½" (0.5 inches) or 1.5 cm.
Pattern Name: Optional label for the pattern you are cutting fabric for.
Fabric Name: Optional label to help you remember which fabric this calculation is for.
Width & Height: Enter the dimensions of each individual pattern piece you need to cut, not including seam allowance — the calculator adds your margins automatically.
Size + Margins column: Shows you the actual cut size of each piece after seam allowance is added to all four sides.
Total squares used: All pieces are added together to give you the total fabric area needed, which feeds into the Results section.
Leave any row blank if you have fewer than 12 pieces — only filled rows are counted.
Margins are added to all sides of each piece (width + margin×2, height + margin×2).
Currency: Choose your currency symbol — it will appear on all cost fields and results.
Full Fabric Length: How many yards (or metres) of fabric you purchased in total. Used to calculate cost per yard and cost per square inch.
Fabric Price: The total price you paid for the fabric before any discount.
Discount: Any amount subtracted from the price (coupon, sale, etc.).
Shipping, Tax, Other: Any additional costs added on top of the fabric price. All are included in the Receipt Total.
