Leather belt pattern — your own dimensions

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

Parametric belt with a pointed tip, a fold for the buckle, and a separate belt loop. In manual-stitch mode, the patterns include pricking holes. The number, diameter, and spacing of adjustment holes, the distance from the tip, and the dimensions of the tongue slot are configured separately.

Fold for buckle	60
Tip length	30
Strap loop blank length	88
Strap loop width	12
Number of buckle holes · 0 = none	5
Buckle hole diameter	4
Buckle hole spacing	25
From toe to nearest hole	90
Tongue slot length · 0 = no slot	20
Tongue slot width	5
Leather thickness	3
Seam offset from the edge	3

Parts in this example

The dimensions below are derived from the geometric model. The parts list changes with the parameters and enabled options.

Piece	Size, mm
Strap strip	1150.0 × 35.0
Belt loop	88.0 × 12.0

How the size changes the pattern piece

Calculated example: the “overall blank length” parameter was changed from 1150 to 1265 mm. The diagram shows the “Belt strap” 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.

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, 6 sheets PDF patterns, 1:1 SVG patterns, 1:1 DXF patterns, mm JSON 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

Before punching, check the circumference and buckle: the initial holes are a test layout. Select the fold fastener separately. Fit the belt loop around the belt and join it with an 8 mm overlap; align the paired rows of holes.

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

Open the model and set the dimensions in millimeters. To reproduce the tabular example, first load its JSON.
Check the parts list and enabled options. Adjust the seam and dimensions for your material.
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: Stitching line. Dimensions in the piece table and the outer cutting contour may differ because of the seam allowance. How to check seam allowances and stitching lines.

Questions about this construction

Do the patterns include pricking holes?

Yes. Manual stitching adds holes with the selected spacing and diameter along the belt outline and at the ends of the belt loop. Buckle holes and the tongue slot have separate settings. They are included in PDF, SVG, and DXF; a value of 0 disables the number of holes or the slot length.

Can the hole size be changed for my buckle?

Yes. The construction pieces specify the diameter, number, spacing, and offset of the adjustment holes, as well as the length and width of the tongue slot. Before punching, compare the pattern with the actual hardware.
