What is the size of 3"x5" index card? Is it 1/8 or 1/4?

Question

And if it's 1/4, what are the dimensions of a 1/8 index card? Thanks.

Answer 1

1/4 or 1/8 of what?



To be 1/4 of something, it'd have to be 12 by 20 inches. To be 1/8, it'd be 24 by 40.



I do not know of any standard paper units in those sizes.



There are index cards in 4x6 and 5x8, and apparently 2.9x4.1



You can look up the various A-format paper sizes if you like.

Answer 2

Essentially the most long-established measurement for index cards is three through 5 inches (76.2 with the aid of 127.0 mm), for that reason the fashioned title three-by means of-5 card. Different sizes greatly available include 4 by using 6 inches (one zero one.6 by way of 152.Four mm), 5 via 8 inches (127.0 by 203.2 mm) and ISO-dimension A7 (74 by means of a hundred and five mm or 2.9 with the aid of 4.1 in). So 4x6 is 1/4

Answer 3

I think it's 1/8
