How to make printable flashcards
- Type one card per line as
front | back, for examplephotosynthesis | how plants turn light into food. You can also paste two columns straight from Excel or Google Sheets, or use a semicolon, “ = ” or “ - ” between the two sides. - Choose the card size: 3 × 5 inch index cards are the classic study size; 2.5 × 3.5 in (playing-card size) suits vocabulary; 4 × 6 in fits longer answers.
- Choose how to print: double-sided, fold-over, or fronts only (for quiz cards or labels).
- Download, print at 100% and cut along the dashed lines with a paper trimmer or scissors.
Printing double-sided so the answers line up
In double-sided mode every sheet of fronts is followed by a sheet of backs. The backs are laid out as a mirror image, column by column, so after the paper is flipped each answer sits exactly behind its question.
- Portrait pages (most sizes): print on both sides and choose flip on long edge.
- Landscape pages: choose flip on short edge. The tool tells you which one to use under the preview.
- Not sure? Print the first two pages on one sheet, hold it up to a window and check that the cut lines match before printing the rest.
- Printers without automatic duplex: print the odd pages, put the stack back in the tray turned over, then print the even pages.
How many flashcards fit on a page?
| Card size | Double-sided (A4 / Letter) | Fold-over (A4 / Letter) |
|---|---|---|
| 3 × 5 in index card | 4 per page | 2 per page |
| 2.5 × 3.5 in | 9 (A4) / 8 (Letter) | 4 per page |
| A7 (74 × 105 mm) | 4 per page | 2 per page |
| 4 × 6 in | 2 per page | too wide, use double-sided |
So 100 index-card flashcards printed double-sided take 25 sheets of paper (50 printed pages).
Tips for flashcards that work
- One idea per card. Short questions are remembered better than long ones, and the text stays large.
- Use card stock (160–200 g/m², 60–110 lb) so the answer doesn’t show through and the cards survive shuffling.
- Number the cards if you’ll sort them into “know it” and “review again” piles (spaced repetition), so a dropped deck is easy to reorder.
- Language cards: put the word on the front and the translation plus an example sentence on the back.
The text is printed in a standard PDF font, which covers English and Western European letters (é, ñ, ü, ß and so on). Other scripts are not supported yet.
Frequently asked questions
How do I make double-sided flashcards?
Type one card per line as “front | back” (or paste two columns from a spreadsheet), choose “Double-sided” and download. Print on both sides with the flip setting the tool shows (long edge for portrait pages, short edge for landscape), then cut along the dashed lines.
Why are the backs in a different order?
On the reverse side the columns are mirrored, so when the sheet is flipped each answer lands exactly behind its question.
My printer can’t print on both sides. What now?
Choose “Fold-over”: the front and back are printed side by side; cut out each pair, fold along the middle line and glue or tape it.
What size are the cards?
3 × 5 inch index cards by default (the classic study card), or 4 × 6 in, 2.5 × 3.5 in (playing-card size), A7 or half a page.
How many cards can I make?
Up to 500 in one PDF. Long answers are fine: the text shrinks to fit each card.
