About Architect Scale · 1:200

Pulled back to 1:200 for site-wide views. A 5 mm cell now equals one metre, letting you fit a small block of buildings onto a single A3 sheet without losing measurability. Major bold lines at 25 mm give you a 5 m site rhythm. Further reading: A practitioner reading list covers the standards lineage in more depth.

Standards lineage

Preferred scale per ISO 5455:1979 for site and block plans.

A short history

1:200 emerged as the standard intermediate scale between building and master plan when British and German practices standardised on metric sheet sizes in the 1970s.

Where designers reach for it

  • Block plans showing buildings in their site context
  • Landscape and hard-surface layouts
  • Master-planning studies for a single plot
  • Routing diagrams for service runs across a campus

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.
