What Bag Calculator does
Bag Calculator is a free interactive planning tool hosted on Clothing Digest that estimates canvas fabric requirements for sewing projects. Users input project dimensions, the number of pieces, and fabric width to receive total yardage calculations that include a 15% waste allowance. The interface offers preset project types—such as Tote Bag, Kitchen Apron, and Pillow Cover—or a Custom Size option for manual entry. Results display the total yardage needed and confirm that waste allowance is included, helping sewers avoid underbuying material.

Bag Calculator FAQ
- Can I use this calculator for fabrics other than canvas?
- The preset Tote Bag dimension of 17 × 15 inches serves as a starting point; you can adjust the length and width to match your specific tote design.
- Does the calculator account for fabric pattern direction?
- The calculator provides total yardage needed; it does not generate a visual fabric layout diagram or show how pieces fit on the width.
