Scale any pattern up or down by percentage or by a specific measurement. Lock seam allowances, hardware sizes, and zipper lengths so they stay fixed while everything else scales.
Get well-fitting gussets every time. Enter your bag dimensions and the calculator handles the math for gusset length, width, and zipper panel sizing.
Get recommended cut lengths for tote handles, shoulder bags, crossbody straps, sling bags, hip bags, and backpacks. Choose a suggested length based on body type, or measure yourself for a custom fit. Take the guessing out of making straps for kids ages 4–7 and 8–12, and petite, tall, busty, plus size, and broad-shouldered sewists.
Built for bag makers, leather workers, and bag designers at every level. Whether you are sizing up a pattern for the first time, calculating gussets for a custom commission, or cutting a pile of straps for a craft show or market, Your Workroom does the math so you can get back to making.
Switch between inches and centimeters. Your preference is remembered every time you visit.

Built by a bag maker, for bag makers. Every calculation is based on real formulas used in real projects.
