Two pen pal letter examples to adapt

These fictional examples are starting points, not real correspondence. Replace bracketed details with your own, and share only personal information you are comfortable exchanging.

First letter — an introduction:

Hello Morgan,

I’m Alex, and I’m glad we decided to write. I wanted a pen pal because I enjoy getting to know someone through the small details of everyday life. On Saturday I made a pot of tomato soup while the rain tapped at the kitchen window. I added too much pepper at first, but a little cream mellowed it out. It made an easy lunch the next day, too. What meal do you like to cook when you have time? Is there a recipe you’ve been meaning to try?

Take care,
Alex

Follow-up letter — a reply:

Printable stationery ideas for happy mail

Printable digital paper can become a writing border, envelope liner, address label, question card, bookmark, recipe card, playlist card, or a small collage sheet. Print a coordinated set once and keep the originals unchanged so you can reuse the design for future letters.

Try it free: download three coordinated 12 × 12-inch papers from the Vintage Office and Postal collection as a printable PDF. These are digital files; no physical paper is mailed. Get the free sample PDF. To see the complete matching design set, open the Vintage Office and Postal digital paper collection; Etsy shows the current regional price and exact files included.

Use the square design with a letter sheet

For a handwritten letter, use a plain US Letter (8.5 × 11 in) or A4 sheet, then add a narrow strip of the patterned paper away from the writing area if you like. The free sample is square digital paper, not a lined Letter or A4 stationery template. Before printing, check the print preview for the paper loaded in your printer. Our guide to printing square paper on Letter or A4 explains how to reduce the design without stretching it.

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.

Five flat extras to include

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.

Can I write a pen pal letter without decorating it?

Yes. A plain letter is enough: share one real story, answer something from the last letter, and ask an open question. Add a creative extra only if you want to; the conversation matters more than decoration.

How do I keep track of an unfinished reply?

Note when the letter arrived, what you have answered, and one open question to return to. That small reminder can help you pick up where you left off. See our practical reply-log guide for a simple way to track incoming and outgoing letters and open questions.

How can I decorate a pen pal envelope?

For a simple paper accent, line only the inside flap:

1. Open the envelope and trace the inside flap onto plain paper, including the straight edge at the fold. Trim the pattern to sit within the flap outline and leave the sealing strip clear.
2. Place the paper pattern against the inside flap and test the fold. Close the envelope to check that the pattern stays within the flap and the envelope closes; adjust the pattern before cutting printed paper.
3. Before cutting, place the pattern over the printed paper and check which part of the design will show when the flap is open. Mark the fold edge on the back so you can attach the cut piece in the same orientation.
4. Put a few small dots of paper-safe adhesive on the back of the liner and attach it to the inside flap, keeping the envelope’s sealing strip clear. Close the envelope once more.

Keep the outside clear for the delivery address, postage, postmarks, and other mail markings; see the USPS mailpiece standards. The free Vintage Office and Postal sample has three square 12 × 12-inch digital-paper pages; it does not include a ready-sized envelope or lined letter-sheet template.
