    About this paper

    Wulff net (stereonet)

    A Wulff net is the stereographic projection of a sphere’s meridians and parallels. Great circles run from north to south, and small circles curve around the N–S axis. Here they are drawn every 2°, with bolder lines every 10° and N, E, S and W marked around the rim.

    The usual workflow is to pin tracing paper over the center, plot your data on it and rotate it over the net to measure angles. Choose 5°, 10° or a coarser interval for a lighter net that is easier to read.

    Frequently asked questions

    What is the difference between a Wulff net and a Schmidt net?

    A Wulff net preserves angles (stereographic projection) and is standard in crystallography. A Schmidt net preserves area and is preferred for statistics on many geological measurements. This generator draws the Wulff net.

    How do I make sure the grid prints at the right size?

    In the print dialog choose “Actual size”, “100%” or “No scaling”, and turn off “Fit to page” or “Shrink to fit”. To confirm, print our free calibration test sheet and measure the 10 cm line with a ruler.

    Is it free for commercial use?

    Yes. There is no account, no watermark and no download limit. You can use the paper for classes, worksheets, products and client work.
