Measuring Tips

How to measure without a ruler or tape measure?

If you don't have a ruler or tape measure handy, you can try to measure with a standard credit card, which has a width of 3 ⅜ inch or 8.56 cm and a height of 2 ⅛ inch or 5.4 cm.

If you do a lot of online apparel shopping, accurate body measurement using a tape measure is a must. The actual tape you choose doesn’t matter that much. This retractable one is very easy to use, and the fact it uses both CM and IN is extremely helpful.
