Measuring insoles is an important step in determining the best shoe fit, especially when purchasing online or selecting shoes without first trying them on. The interior length and width of the shoe are determined by the insole measurement, giving maximum comfort and support for your feet. 

We will lead you through the step-by-step process of how to measure insole to ensure you obtain the best fit for your footwear in this detailed guide.

Tools Required for Measuring Insole

Before you begin, gather the following tools to accurately measure the insole:

  • A ruler or measuring tape
  • A flat surface
  • A piece of paper

Step-by-Step Guide How To Measure Insole

Follow these simple steps to measure your insole accurately:

Step 1: Prepare the Shoe

Place the shoe to be measured on a flat, even surface. Make sure the shoe is clean and clear of debris on the inside.

Step 2: Flatten the Insole

Gently smooth the insole with your fingers to remove any wrinkles or bumps that may alter the measurement.

Step 3: Position the Paper

Insert the paper into the shoe, covering the entire length of the insole. Check that it is flat and evenly positioned.

Step 4: Trace the Insole

Trace the outline of the insole on the paper with a pen or pencil. Ascertain that the tracing is precise and follows the curves of the insole.

Step 5: Measure the Length

Trace the length from the heel to the tip of the toe with a ruler or measuring tape. This measurement should be taken in either inches or centimeters.

Step 6: Measure the Width

Position the ruler or measuring tape at the broadest place of the insole tracing (typically around the ball of the foot) to measure the width. Take note of this as well.

Step 7: Determine the Shoe Size

Compare the dimensions to a shoe size chart or a shoe size calculator to get the shoe size that corresponds to the length and width of the insole.

Tips for Finding the Right Fit

  1. Add Extra Room: To ensure a comfortable fit, add a little extra room (around 1/4 to 1/2 inch) to the measured length to accommodate your foot’s movement.
  2. Consider Shoe Type: Because different shoe kinds may fit differently, it’s critical to try on a variety of shoe styles to discover the best fit for each.
  3. Shop in the Afternoon: Because feet swell significantly over the day, measure your insoles and try on shoes in the afternoon for a more accurate fit.
  4. Check for Shoe Widths: Consider the width of the shoe in addition to the length to get a fit that gives enough support for your foot shape.


Measuring insoles is a simple but critical step in determining the best shoe fit. You may confidently shop for shoes online or in physical stores if you have the necessary equipment and correct measurements. 

To ensure a comfortable and supportive fit for every step you take, keep your foot comfort, shoe type, and shoe width in mind.
