What the AI looks for in Index Cards
- Size
- 3 x 5 in for flashcards, 4 x 6 or 5 x 8 in for recipes and notes Size must match your card box or file and the amount you write per card.
- Ruling
- Ruled on one side, blank on the other, for flashcards Question on the blank side and answer on the ruled side is the standard study layout.
- Bleed-through
- No show-through with gel pens and highlighters Thin cards make two-sided use useless.
Brands that matter
- Oxford: The long-standing default for index cards in many sizes and colors.
- Mead: Widely available budget alternative.
What to avoid
- Thin bargain cards that curl and show ink through
- Buying 4 x 6 cards for a 3 x 5 file box
