Choose the correct size measurement

Full circle diameter and radius refer to the circle the shape comes from. Shape width refers to the visible width before rotation. These are not always equal: a right-facing semicircle is half the full circle diameter wide and a full diameter tall.

Half, quarter, three-quarter and eighth circles

Choose 180°, 90°, 270° or 45° shapes. Rotate in degrees, mirror horizontally, and add a center point or center cross. Keep the initial orientation or use 90° steps to turn the straight edge.

Frequently asked questions

Can I print a very large semicircle?

Yes. The generator splits oversized templates into tiles without shrinking them. Align the overlap shown on each page.

Does the width setting include rotation?

No. Width is measured before rotation. Rotating changes the bounding box on the page.
