Finding Inch Fractions on a Tape Measure
Finding measurements on a ruler or tape measure can be confusing at first, but once you understand how the marks are laid out then it is far simpler. The markings between the larger inch numbers vary in length.
The longest markings will be the quarter inch markings, ie. the first marking is 1/4 inch, the second is 1/2 (2/4) inch, the third is 3/4 inch.
The next longest markings will be the eight inch markings, ie. the first marking is 1/8 inch, the second is 3/8 inch, the third is 5/8 inch, etc.
The next longest markings will be the sixteenth inch markings, ie. the first marking is 1/16 inch, the second is 3/16 inch, the third is 5/16 inch, etc.
