Custom Flashcards

Front and back, aligned for duplex printing

Type the pairs and the sheet prints the fronts on one page and the backs on the next, with the back grid mirrored left to right.

That mirroring is the part that is easy to get wrong by hand and annoying to discover after cutting. Print double-sided, flip on the short edge, and every back lands behind its own front. Flip on the long edge instead and the deck comes out with the answers behind the wrong questions.

Cards per page

Four, six or eight. Four gives large cards that are easy to read across a room and hold a full definition. Eight gives a pocket deck.

Match the size to the length of the backs. A one-word answer works at eight to a page; a two-sentence definition set at that size is small enough that people stop reading it and start guessing from the first few words.

Why flashcards work, and the way most people use them wrongly

They work because of retrieval. Looking at the front, failing to recall, and then seeing the back is a stronger memory event than reading both sides together — and the failed attempt is part of the mechanism, not a waste of it.

The common mistake is to read through the deck rather than testing with it. A card looked at is not a card recalled, and a deck read three times feels productive while doing very little.

The second mistake is not separating the deck. Cards you get right should be tested less often than cards you get wrong; keeping them in one pile means most of your time goes on the ones you already know.

Writing good pairs

One idea per card. A back with three facts on it will be recalled partially, and partial recall is hard to grade honestly.

Make the front a real question where you can. "Cat" tests nothing in particular; "What is the French for cat?" has one right answer and you know immediately whether you had it.

Keep it reversible. A good pair works in both directions, and a deck you can turn round and run backwards is worth twice as much as one that only goes one way.

Setting it up

A title, your list of front/back pairs, and cards per page. A4 or US Letter.

Printing

Card, or paper glued to card — on plain paper the back shows through the front, which defeats the object entirely.

Print at 100% so the fronts and backs stay in register. Any scaling applied to one page and not the other puts the whole deck out of alignment.
