Index cards come in a range of sizes so you just need to think about what you use the cards for and buy the most appropriate size. The most popular we sell is the 127x76mm index card which is about double the size of a standard business card - enough for a name and address to be written on. The other two popular sizes of index cards are the 203x127mm which is a similar shape but just with greater space and the 152x106mm size which is slightly more square.
We stock index cards from several brands and all are of a similar quality. 5 Star index cards are the most cost effective cards and are of a good quality. Aside from 5 Star the most popular brand are Concord index cards - they have a wide range of products in 4 different sizes including the most popular 3 sizes mentioned above.
