Medium Format Aspect Ratio Calculator
Use this medium format calculator to convert classic film frame shapes and modern digital medium format dimensions without ratio drift.
Medium format photography includes multiple frame families rather than one single ratio. 6x6 provides square framing, 6x7 provides portrait-friendly composition, and 6x4.5 aligns closely to 4:3 behavior. Digital medium format systems commonly use 4:3 or 3:2 depending on sensor design.

Practical Tips
- Choose the final print ratio before scanning or exporting medium format captures.
- Square 6x6 originals are flexible masters for both portrait and landscape crops.
- 6x7 captures often adapt well to print workflows requiring stronger vertical structure.
A reliable process is to preserve one source-ratio master export first, then generate each destination ratio as a deliberate derivative. This keeps your archive clean and reduces repetitive cropping work.
When output requirements change between web galleries, socials, and print labs, this calculator gives you quick conversions while preserving composition control.
