Use this bag capacity calculator to estimate what may fit inside a finished handbag, tote, purse, project bag, travel bag, or diaper bag.
Enter the finished height, width, and depth of the finished bag pattern measurements. The calculator will estimate the bag’s general size category and give examples of everyday items that may fit inside.
This can help you compare bag sizes before choosing a sewing pattern, resizing a pattern, or deciding whether a finished bag will work for your needs.
Helpful Tip: For the best comparison, measure a bag you already own and like. Measure the height, width, and depth, then enter those measurements into the calculator.
You can also enter the finished measurements from a sewing pattern to get a better idea of what the completed bag may hold.
Keep in mind that bag shape matters. A wide tote, narrow crossbody bag, rounded purse, boxed-bottom bag, or zip-top bag may all hold items differently, even if the basic measurements are similar.
Please Note: This calculator gives an estimate only. Actual usable space may vary based on the bag shape, opening size, boxed corners, curves, pockets, lining, stabilizer, padding, and construction method.
