About Architect Scale · 1:100

The most-used scale in European architectural practice, here printed as a ready-to-use grid. Every 10 mm square represents one square metre on site, so a 5 m × 4 m room snaps neatly into a 50 mm × 40 mm patch on the page. Bold every-fifth-line hatching gives you a 5 m reference rhythm. Further reading: A practitioner reading list covers the standards lineage in more depth.

Standards lineage

Recommended preferred scale per ISO 5455:1979 for building plans.

A short history

1:100 plans came to dominate European practice once the A0–A4 ISO sheet sizes were widely adopted, since most domestic-scale buildings fit cleanly onto an A2 or A3 sheet at this ratio.

Where designers reach for it

  • Whole-building floor plans
  • Planning-application drawings
  • Site layout at building scale
  • Tender drawings for general contractors

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.
