A Mail Scale and measuring tape are both required tools when managing mail. Weighing and measuring mail items is extremely important when handling mail items. Please weigh and measure all packages when inserting mail and when shipping mail items, to ensure correct postage is calculated. 

Note: Regular sized letter envelopes and postcards do not need to be weighed. The system automatically inserts 30 grams or 1oz for these mail items.

A Mail Scale is used to determine the weight of letters, flats, packages and to calculate accurate postage or shipping costs. 

A flexible measuring tape is recommended and typically used to measure the dimensions of a package or mail item accurately measure the mail item, especially when the mail item is irregular or curved.
