What is a "Fraction"

When measuring vertical blind replacement slats, a fraction is used to express the length or size of the slats. It represents a part of a whole measurement in terms of inches.

For example, let's say you measure a vertical blind slat to be 35 inches long. In this case, there is no fraction representing the length of the slat  because it is the whole measurement.

But, let's say the slats is a bit more:



When measuring in 1/8" increments, fractions are used to represent measurements that are a multiple of 1/8 of an inch. Here's how fractions work in 1/8" increments:

  • The smallest unit is 1/8 of an inch, represented as 1/8".
  • 1/4" 
  • 3/8" 
  • 1/2"
  • 5/8" 
  • 3/4", 
  • 7/8" 

In summary, when measuring in 1/8" increments, fractions are used to express lengths or sizes that are multiples of 1/8 of an inch, ranging from 1/8" to 1 inch. Each fraction represents the number of 1/8" increments in the measurement.
