PD Measurement

PD, or Pupillary Distance, is the distance between your pupils. It's a crucial measurement for ensuring the perfect fit of your glasses. Measuring your PD is now easier than ever with our new camera-based PD measurement tool.

Camera-Based PD Measurement

Our camera-based PD measurement tool utilizes the camera on your mobile device or computer to provide you with an instant and precise measurement. For the most accurate results, we recommend using an iPhone, as it takes advantage of the depth-sensor in the front-facing camera.

1. Click "START NOW" below.
2. Grant camera access if prompted.
3. Follow the on-screen instructions to position your face correctly.
4. Get your instant and precise PD measurement.


We've designed this tool to be quick, user-friendly, and highly accurate, ensuring you have the most precise PD measurement for ordering your glasses.

Don't have a camera-enabled device? No worries! We also offer a print and measure method for obtaining your PD. Click on the download link below to get started.

At Kits, we're dedicated to providing you with a seamless and customer-focused eyewear experience. With our easy-to-use PD measurement tools, you can confidently order glasses that fit you perfectly.

Let's get started on your journey to impeccable vision! Choose your preferred method below:

1. Use Our Online PD Measurement Tool

Grab a regular card with a magnetic stripe on the back. Student IDs, credit cards and gift cards work well to start our online PD tool.

2. Use Our Paper PD Measurement Tool

You may have received our paper PD measurement tool in your recent online order. In order to use this tool, place the ruler on your eyes so that the "0" lines up at the centre in between your eyes. Add up the two numbers, to get your PD. See example below:
