Classic 4:3 frames for animatic and educational-video storyboards.
A storyboard sheet using the classic 4:3 academy ratio - still the right choice for educational video, broadcast-archive material, and vintage-feel animatics. Further reading: A practitioner reading list covers the standards lineage in more depth.
Frame aspect matches SMPTE 1.33:1 academy ratio.
The 4:3 academy ratio was set by the Academy of Motion Picture Arts and Sciences in 1932 and dominated film and television until widescreen took over in the 2000s.
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.
