Interactive Tarp Tent Generator

Support the development of more free tools

These free tools take up a large amount of my limited personal time, so any support is greatly appreciated!

Design single pole tarps and trekking pole tents using this free interactive pattern generator. Use the interactive view to move the corner points or input values, and then use the interactive pattern canvas to experiment with orientations to maximise fabric usage

Version 7 May 2026. There might be bugs. Test pattern with a scaled model or paper first.

3D View: Approx. 6ft Person

Catenary Curve Depth: 2 cm/m 2 cm/m recommended

Adjust the depth of optional catenary cuts along the ridgelines. These can help with a tighter pitch but reduce headroom

Top-Down Plan View (Interactive)

Click a corner to manually set coordinates, or drag corners and apex

Manual Editor

The `baseCornersRelative` coordinates are relative to the `apexAbsolute` position (e.g., `rel_x: -100` means 100cm to the left of the apex), in clockwise order from top-left. The visualiser will update when you click away from this text box.

3D View

Drag to rotate, scroll to zoom Download as .OBJ.STL

The 3D preview of catenary cut designs is a visual approximation and does not simulate the fabric stretch taken out by the catenary cuts. Use the 2D pattern pieces generated below rather than trying to flatten the 3D model to make your pattern pieces.

Pattern Layout

Drag and rotate the pattern pieces to see how they fit on your fabric roll width. Export to a 1:1 scale svg and edit in Inkscape, Illustrator, Affinity, or similar vector image editing software for more detailed pattern adjustments.

This is the 'cut line' geometry (side lengths and angles) for each panel, calculated based on the 3D tent shape. This data can be copied for external use
