What Paying for Speed Actually Buys, Journey by Journey

Express saves 2 days on a letter across town and 16 days on one going abroad. The extra money is worth wildly different amounts depending on how far the letter has to go.

Posting Backwards From a Birthday

Cards arrive late because people post them forwards. Start at the date it has to arrive, subtract the slow end of the range, add a few days of slack, and the posting date works itself out.

What It Costs to Write Abroad, and Where the Multiple Bites Hardest

An international letter is 2.1 times the domestic price. A small package abroad is 2.7 times. The multiple is not constant — and knowing where it is worst decides what you send.

How Long Your Letter Takes to Read, and Who It Suits

A 400-word letter takes an adult 1.7 minutes and a six-year-old 5. Writing for a younger pen pal is mostly a question of length, and length is the easiest thing in the world to check.

Why a Pen Pal Replies Once a Month, Not Once a Week

An international letter takes 7–21 business days each way. Double it for the round trip, add a few days to actually write back, and a reply cycle is 3.8 to 9.4 weeks. Nobody is ignoring anybody.

Twelve Hours Apart Is Where the Conversation Gets Hardest

Up to twelve hours apart, every hour of time difference costs an hour of shared waking time. At twelve there is one hour left, and past that the window opens again on different calendar dates. That is the number that decides whether a friendship happens live or by post.

One Sheet of Paper, Four Folds, Four Different Envelopes

The same sheet of US Letter needs a 9 x 12 flat envelope unfolded and a No. 10 tri-folded. The fold is not a tidying decision — it decides the envelope, and the envelope decides the postage.

Two Stamps Cover More Than You Think

Two $0.82 stamps cover a 2 oz letter with 53¢ to spare — and they also cover a 3 oz one. The third ounce is free, and almost nobody uses it.

One Thick Letter Costs Less Than Two Thin Ones

The first ounce costs $0.82 and every ounce after it costs $0.29. That single fact decides almost every question about what to put in an envelope.

The Tenth of an Ounce That Costs 87¢

A 3.5 oz letter costs $1.69. Add one more tenth of an ounce and it stops being a letter at all, and the price jumps to $2.56.
