>>1721859>>1721859They're quite similar to DIN paper formats and their doubling sizes (with ~sqrt2 aspect ratio so the aspect ratio remains the same), but euro boxes don't have such an aspect ratio, they range from 200x150 to 800x600 so the aspect ratio switches between 4:3 and 3:2 with every doubling, with the most useful sizes probably being 400x300 (the same as medium veggie crates, large beer crates and a lot of water crates) and 600x400 (the same as large veggie crates). Commonly available heights range from 70mm to 320mm in 50mm steps, no idea how this came to be, with beer crates being 300mm tall and water crates being up to 370mm tall. They're also available with a wide variety of clear sides, opening side lids, open sides, carrying handles or different types of top lids. Also 400x300 euroboxes are the perfect size to fit into IKEA's IVAR shelving system with its 400x300 and 800x300 shelves.
