Tote/Bag Size & Fabric Calculator
Calculate fabric needed for a tote bag from finished width, height, gusset depth, and handle length.

How tote bag fabric is calculated
This calculator treats the tote body the same way as a box cushion: two main panels (front and back), each the finished width and height plus seam allowance, plus a gusset strip that wraps around the sides and bottom if the bag has depth. The gusset's length equals the bag's perimeter along the sides and bottom, and its width equals the gusset depth plus seam allowance.
Handles are calculated separately and added to the total: two handles, each cut to your specified length and width (which typically gets folded and stitched down to a narrower finished strap), using a small additional length of fabric on top of the body panels and gusset.
This follows standard bag-making construction for a basic gusseted or flat tote with sewn-on fabric handles.
Worked example
A 16 × 14 inch tote, 4-inch gusset, 0.5-inch seam allowance, two 26-inch handles, 44-inch fabric.
Real-world context
Reusable grocery totes and market bags are one of the most common bag-sewing projects, and getting the gusset depth right upfront determines whether the finished bag can actually hold a reasonable grocery load or ends up too shallow and awkward to pack — planning fabric before cutting avoids discovering a too-small gusset only after construction.
Matching fabric for multiple totes made as a batch (like holiday gift bags for a group) benefits from calculating combined yardage in advance, since buying one larger cut of fabric is often more efficient and cost-effective than several smaller separate purchases.
Common misconceptions
"A flat tote and a gusseted tote need about the same fabric." Not usually. The gusset strip on a boxed-bottom tote adds meaningfully more fabric than a flat, two-panel tote of the same width and height, similar to how a box cushion needs more fabric than a flat pillow cover.
"Handle fabric is negligible and doesn't need planning." It adds up. Two long handles can use a meaningful amount of extra fabric, especially on a bag already sized close to a fabric width limit — always include handles in the total calculation, not just the body panels.

Frequently asked questions
What is a gusset on a tote bag?
A gusset is the side/bottom panel that gives a bag depth, turning a flat two-panel pouch into a bag that can actually hold volume — set gusset depth to 0 for a flat tote with no boxed bottom.
How long should tote bag handles be?
Shoulder-carry handles are typically 24-28 inches finished length (before folding/sewing); shorter hand-carry handles are often 18-20 inches — this varies by personal preference and how the bag is meant to be worn or carried.
Does this include lining fabric?
No — this calculates the main shell fabric and handles only. If your tote is lined, use the Lining Fabric Calculator separately, treating the tote body dimensions the same way.
Should I add extra for interfacing or stabilizer?
A structured tote often uses interfacing or a stiff stabilizer on the main panels; calculate that separately using the Interfacing/Stabilizer Yardage Calculator based on the same panel dimensions.
