Weight and size of a box of 50 sheets of 4x5?

[Athiril]

Hi,

I measured my Pro 160S box of 10... 12x15cm by about 2cm thick, feels like about 100g, I want to calc postage for a box of velvia 4x5 50 sheets instead of getting ripped off on postage

Ive estimated both 500g and 800g and 4cm thick for postage options.

A 50 sheet box of 4x5 Tri-X 320 (new) weighs 289.9 grams -- which is two grams heavier than the new TMax400. It is 3.2 cm thick -- both boxes are the same -- actually 145mm x 116mm x 32mm.
