Keep handmade letters mail-friendly

Use thin paper, flat stickers, and lightweight inserts. Avoid loose glitter, rigid objects, and bulky decorations that create uneven thickness. Leave the address area clear and high-contrast, then check the latest postal rules for your destination before adding postage.

United States letter guide

USPS defines letter-size mail as rectangular and within its published size, thickness, and weight limits. Bulky or uneven contents can make a letter nonmachinable, so measure the finished envelope rather than the empty one. See the official USPS physical standards for letters.

Canada letter guide

Canada Post currently separates standard Letter-post from non-standard or oversized items by finished size and weight. A standard domestic letter can be no more than 245 × 156 × 5 mm and 50 g. Confirm the latest limits on the official Canada Post size and weight page.

Frequently asked questions

What should I write in a first pen pal letter?

Introduce yourself with a few specific details, explain what made you want to write, share one short story, and ask two easy open-ended questions. Avoid sending sensitive personal information until trust has developed.

How long should a pen pal letter be?

One or two pages is enough when the content is specific and easy to answer. A shorter regular letter is often better than a long one that becomes difficult to finish.

Can I print stationery on both sides?

Yes, if the paper is opaque enough and the design leaves a calm writing area. Print one test sheet first to check show-through and readability.

What is a safe flat extra?

A bookmark, small art print, recipe card, playlist card, or a few lightweight paper die cuts can work. Check the finished envelope against current postal rules.
