About Polar · 5° Sectors

Polar coordinate paper with concentric circles spaced at uniform radial increments and radial spokes every 5°. Ideal for plotting any quantity that depends on angle: antenna radiation patterns, wind-rose climate diagrams, or the famously circular rose-petal mathematical curves. Further reading: A practitioner reading list covers the standards lineage in more depth.

Standards lineage

Polar coordinate convention follows ISO 80000-2:2009 mathematical notation.

A short history

Polar paper became the standard medium for radio-engineering antenna characterisation in the 1920s and 30s as broadcast technology spread.

Where designers reach for it

  • Antenna radiation pattern plots
  • Wind-rose climatic data
  • Radial sun-path diagrams
  • Polar-coordinate calculus exercises

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.
