# Three IPD Presets to Rule Them All, and a Handy Trick for Those of Us in Between
Virtual reality (VR) technology has advanced significantly, and devices like the **Meta Quest 3S** are redefining immersive experiences. Yet, one vital component of enjoying VR is frequently neglected: the **Inter-Pupillary Distance (IPD)**. Correctly setting your IPD is vital for an enjoyable and nausea-free VR experience. In this article, we’ll guide you through the three IPD presets on the Meta Quest 3S, how to accurately measure your IPD, and a handy trick for those whose IPD doesn’t neatly align with the presets.

## The Importance of IPD in VR
IPD signifies the distance between the centers of your pupils, which varies among individuals. In VR, the headset lenses must align with your eyes to ensure a clear and comfortable visual experience. Incorrect IPD settings may lead to:
– **Blurry images**
– **Nausea**
– **Headaches**
– **Challenges in distance perception**
For instance, in games like *Beat Saber*, having the wrong IPD setting can hinder your ability to accurately slice blocks because your brain finds it difficult to assess the distance between objects. Thus, identifying the correct IPD setting is essential for the best VR experience.

## Measuring Your IPD
Before adjusting your Meta Quest 3S, you’ll need to measure your IPD. Here is a straightforward method that requires only a **ruler with millimeter markings** and a **mirror**:
### Measuring IPD Steps:
1. **Shut your left eye** while gazing into the mirror.
2. With your **right eye open**, focus directly on your right pupil.
3. Position the ruler just below your eye, centering the **zero mark** on your right pupil.
4. **Close your right eye** and **open your left eye**, keeping the ruler steady.
5. Look directly at your left pupil and **record the millimeter distance** that corresponds with the center of your left pupil.
For example, if the distance between your pupils measures 66mm, that’s your IPD. The typical IPD is around 63mm, although it can range from 55mm to 72mm or more.

## Adjusting the IPD on Meta Quest 3S
Now that you have your IPD measurement, it’s time to adjust your Meta Quest 3S. The Meta Quest 3S has **three IPD presets**:
– **Preset 1:** 58mm
– **Preset 2:** 63mm
– **Preset 3:** 68mm
By default, the Meta Quest 3S is set to **Preset 2**, covering the average IPD. Here’s how to configure the lenses to align with your IPD:
### Adjusting IPD Steps:
1. **Identify which preset** is closest to your IPD measurement.
– If your IPD measures around 58mm, select **Preset 1**.
– If your IPD is about 63mm, opt for **Preset 2**.
– If your IPD is approximately 68mm, choose **Preset 3**.
2. **Grip the Meta Quest 3S** and grasp the gray cover on one lens’s outer edge.
3. **Gently shift the lenses** closer together to reduce the IPD or further apart to increase it.
Once you’ve adjusted the lenses to the correct preset, you should experience a clearer image, leading to a more pleasant VR adventure.

## What If My IPD Doesn’t Align with the Presets?
Not everyone’s IPD will perfectly correspond to the three presets. If your IPD is somewhere between the presets, don’t be concerned — there’s a handy trick to help you attain a more precise setting.
### The Trick for IPD Measurements in Between:
If your IPD is, say, 60mm or 66mm, you can adjust the lenses **between the preset points** for a more comfortable fit. Here’s how to do it:
1. **Hold the Meta Quest 3S** and grasp the gray plastic on the outer side of one lens.
2. **Gently push the lenses** inwards or outwards, stopping just **past the nearest preset** to your IPD.
3. If you encounter issues, try adjusting the lenses from a higher preset and gradually moving them inward.
This technique enables you to fine-tune the IPD closer to your specific measurement. For instance, if your IPD is 66mm, you can tweak the lenses to sit just between **Preset 2 (63mm)** and **Preset 3 (68mm)** for enhanced comfort.
