How to Choose the Right Cellular Shade Size

Shopping for honeycomb or cellular shades can be confusing when it comes down to the choice between the wide range of cell sizes on the market. 3/8″, 7/16″, 1/2″…what does it all mean? Well, we’re here to help.

The fractional measurements included with each product represent the size of the cell created by the two pieces of fabric. Differences in cellular shade sizes may seem minuscule  but we’ll help you compare the different industry offerings to find the look that suits your window best.

We’ve organized the cell measurements into three categories: Small (3/8″), Mid-Size (9/16″ and 1/2″), and Large (3/4″) to help you understand what these numbers really mean when it comes to your window.

Small Cellular Shades: 3/8″ Cells

  • Look proportional in smaller windows – small cells are too busy on a large scale.
  • Can fit in windows with shallower depths.
  • Great for bathrooms – add insulation and maintain privacy with no route holes.

Honeycomb shades with a 3/8″ cell measurement and under are generally classified as small cellular shades. Shades in this range are most often recommended for smaller windows. With a reduced measurement, the fabric cells have a narrower width that allows them to fit in shallower window openings that may not be able to accommodate larger cell sizes.

Did you know that the largest percentage of air leakage in your home occurs through the windows?

The largest size of cellular shades we offer is 3/4″.  This significantly larger cell construction is perfect for wider picture windows because larger cell fabric is lighter per square foot than other sizes. With this reduction in weight, a shade that spans a large opening will be able to support itself with no threat of sagging or need for extra reinforcements.
