Trimetric grid with three independent foreshortening ratios.
Trimetric projection assigns a different foreshortening factor to each principal axis, which gives the most natural pictorial of the orthographic family at the cost of being harder to measure. This template provides the underlying angled lattice; mark your own scale ratios on each axis to suit the subject. Further reading: A practitioner reading list covers the standards lineage in more depth.
Trimetric projection is described in ISO 5456-3:1996 §5.4.
Trimetric grids were prized by Bauhaus draftsmen for industrial-design boards - Herbert Bayer's 1930s appliance studies were almost all trimetric.
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.
