About Polar · 10° Sectors

A coarser polar grid with 10° radial divisions, easier to read at distance and well-suited to compass-bearing surveys, navigation plots and quick polar-projection sketches. Further reading: A practitioner reading list covers the standards lineage in more depth.

Standards lineage

Polar coordinate convention per ISO 80000-2:2009.

A short history

Marine navigation charts began including polar overlays in the late 19th century as a standard aid for compass-bearing reconciliation.

Where designers reach for it

  • Compass-bearing surveys
  • Marine and aviation navigation plots
  • Solar-azimuth daylighting studies
  • Astronomy planisphere overlays

Printing this grid

Every variant on this page is delivered as a vector SVG with physical millimetre dimensions baked into the file, so a compliant printer driver will reproduce it at exact 1:1 scale by default. Choose the sheet size that matches your printer tray, set scaling to 100 % (never "fit to page"), and verify with the calibration check on our how-to-print guide. Buyer's guide: Comparing the major architectural scale rulers can help you pick the right physical scale rule to use over the printed grid.
