Leather tote bag pattern — custom dimensions

Tote bag pattern: parameters, piece list, and SVG and DXF examples. Change the dimensions in VLOTHO CAD and export your own patterns.

Zippered tote bag: construction example

Tote bag with two handles and a front zip pocket. The top and bottom widths, body height, depth, pocket dimensions, and handle rise can be configured.

How the size changes the pattern piece

Calculation example: the top width parameter was changed from 340 to 374 mm. The diagram shows the Front panel piece before and after recalculation at the same scale.

The dimensions below the drawing refer to the outer cut-edge contour. This is the result of a geometric calculation.

You can also download the modified JSON project. After modification, check the assembly on a mockup.

The files were generated using the standard VLOTHO CAD export from the parameters specified above. They show the model geometry and do not replace checking the product in the material.

PDF A4, 33 sheetsPDF patterns, 1:1SVG patterns, 1:1DXF patterns, mmJSON project

PDF A4 automatically selects portrait or landscape pages and rotates the pieces to reduce the number of sheets. For assembly, a 10 mm overlap, numbers, and alignment marks are provided. The standard PDF contains one piece per page. Both variants include a 100 mm test segment. For your own dimensions, modify the project and export a new PDF. How to print patterns at 1:1 scale.

What to check before cutting

Check the pocket opening size, pocket bag, and distance between the handle attachments. The model's initial dimensions are examples: measure the required capacity and adjust the construction before cutting.

VLOTHO CAD builds a geometric prototype. Allowances for bending, skiving, assembly thickness, and construction methods are determined by your material. Start with a paper mockup and a trial piece.

How to get a pattern for your dimensions

  1. Open the model and set the dimensions in millimeters. To reproduce the tabular example, first load its JSON.
  2. Check the parts list and enabled options. Adjust the seam and dimensions for your material.
  3. Save the project and export a new pattern set. After changing the dimensions, the previous files no longer correspond to the project.

Dimension reference for this model: Baseline. Dimensions in the parts table and the outer cut contour may differ due to the seam allowance. How to check seam allowances and stitching lines.
