How to Use a Brannock Device for Accurate Shoe Sizing

Ever bought shoes that felt too tight or too loose? The secret is often a bad measurement. The Brannock device is the gold‑standard tool shoe stores use to get exact foot dimensions. It measures length, width, and arch length in one go, so you can pick the right size every time.

Step‑by‑Step: Getting Your Foot Length Right

First, stand on a hard, flat surface with your weight evenly distributed. Place your heel against the back stop of the Brannock ruler. Slide the sliding footboard forward until it touches the tip of your longest toe—usually the big toe or the second toe. Read the number on the scale; that’s your foot length in inches or centimeters.

Do this for both feet because most people have a slight size difference. Use the larger measurement as your baseline. If you’re measuring at home, try to do it in the afternoon when feet are slightly swollen from daily activity—this gives a more realistic fit.

Width and Arch: The Details That Make a Difference

The width bar slides left or right. Push it gently until it snugly contacts the sides of your foot without pressing into the skin. The device will show you a width letter—A (narrow) to E (extra wide). Choose the width that matches the reading; don’t guess based on shoe style alone.

For the arch length, place the arch bar at the ball of your foot, where your foot bends. The ruler will indicate the distance from heel to ball. This helps you find shoes with proper arch support. If the arch measurement is high, look for shoes labeled “arch support” or with removable insoles.

Now you have three numbers: length, width, and arch. Most brands convert these into a standard shoe size, but always double‑check the retailer’s size chart. Some online stores list both U.S. and UK sizes, so you can match your measurements directly.

Remember, different shoe types need slightly different fits. Athletic shoes often require a tighter heel and a bit more room in the toe box for movement, while dress shoes should hug the foot without squeezing.

If you’re buying online, use the measurements you recorded to filter results. Many sites let you enter foot length and width, then they show only compatible styles. This saves you from endless returns and makes the whole shopping experience smoother.

Finally, take care of your Brannock device. Wipe it down after each use to keep it clean, and store it flat to avoid bending the ruler. A well‑maintained device will give you reliable readings for years.

With these simple steps you can stop guessing your size and start choosing shoes that feel made for you. The Brannock device does the math; you enjoy the comfort.
