Pay the right amount for your postage. Our postage pricing for letters is based primarily on the size and weight of your letter. Check out our standard and oversize dimensions below.

Standard (50 g or less)

Use a single stamp for items that are within the standard weight and size range.

Maximum dimensions
The maximum dimensions are 245 mm x 156 mm (9.6 inches x 6.1 inches). However, the maximum dimensions for cards and postcards to the U.S.A. or an International destination are 235 mm x 120 mm (9.2 inches x 4.7 inches).

Non-standard and oversize (0-500 g)

Oversize or non-standard size envelopes and postcards will cost you more in postage.

If your letter is larger than the maximum dimensions above you’ll need to use our parcel services. Check out our size and weight limits for letters and documents sent in Canada and U.S.A. and International.
