How to sew a custom tote bag in ANY size (2 styles)

Designing your own tote bag sewing pattern has never been easier. This revolutionary pattern generator is unlike any other tote bag pattern you’ve used. The custom tote bag designer means you never need to buy another tote bag sewing pattern.

Want a bag that’s tall rather than wide – we got you. Want a really long bag so you can fit a yoga mat in the bottom – we got you. Want a huge beach tote with long handles – we got you. Want to make a tiny festive tote that will exactly fit a little gift box to hang on the tree – we got you on that too.

Whatever size tote bag you want to create, the custom pattern generator will give you a visual template and set of measurements to cut your fabric to exactly the right size. No printing needed.

Enter your desired height, width and length, choose your handle drop and seam allowance. The calculator does all the rest for you, displaying your pattern template and cutting dimensions right there on the screen.


One is a SIMPLE design where the whole outside of the bag is a single fabric. Ideal for a quick sew, a plain tote bag, a grocery bag, or a small gift bag. You may pick different fabrics for your outer, lining and handles.

The second design is a split outer fabric where the base of the bag and a section of the outer fabric at the bottom is a different fabric from the top section. This is the SPLIT design as seen below. It’s possible to customize this to have your split seam at any point on the face of the bag. 

This split design is ideal to use for a more sturdy tote bag with a hardwearing vinyl base and pretty fabric above, or for mixing a solid fabric with a print.

  1. Just a suggestion. It would be helpful to tell the sewer what side of the fabric to place the straps. I had to do some picking to remove the strap from the way that I guessed (wrongly) was the correct side to place the strap. I do appreciate you generator and made a HUGE beach bag.
