Actual Image Sizes

What are the actual images sizes in mm for 645, 6x6, 6x7, 6x8, 6x9 & 4x5 ?

Do all camera manufacturers standardise on the same image size for each format ?

Standardized? No!

My Hasselblad only delivers 5.4 x 5.4 cm images, whereas my Rollei E2 is 5.8 x 5.8 cm. 4x5 inch format depends on the film holders, and film packs and Polaroids are different yet.

The "commercial" size is always the same : 6x41/2, 6x6, 6x7, 6x9 etc... But each manufacturer has its own format, depending on the film holder window.<br>

Here are some of the most common formats :<br>

Format 6x4.5 : 56 x 40.5<br>

Format 6x6 : from 56x54 to 56 x 56<br>

Format 6x7 Toyo : 56 x 67<br>

Format 6x7 Horseman : 56 x 68<br>

Format 6x7 Pentax : 55 x 70<br>

Format 6x7 Mamiya RZ : 56 x 69.5<br>

Format 6x7 Cambo-Sinar-Wista : 56 x 70<br>

Format 6x7 Linhof Super Rollex : 56 x 72<br>

Format 6x7 Linhof Rapid Rollex : 57 x 76<br>

Format 6x7 : 56 x 69.5<br>

Format 6x8 : 56 x 76<br>

Format 6x9 Cambo-Horseman-Wista : 56 x 82<br>

Format 6x9 Toyo : 56 x 84<br>
