# How to Use Ruler on iPhone: A Step-by-Step Guide

Measuring things using a ruler is pretty basic, right? But, did you know that your iPhone comes equipped with its very own ruler? Thatâ€™s right! The next time you find yourself without a physical ruler, your trusty iPhone can come to the rescue. With just a few taps, you can measure objects with surprising accuracy. So, letâ€™s get into it â€“ hereâ€™s a quick guide on how to use the ruler on your iPhone.

## Step by Step Tutorial on How to Use Ruler on iPhone

Before we dive into the step-by-step tutorial, letâ€™s talk about what weâ€™re trying to achieve. The iPhoneâ€™s ruler function is part of the Measure app, which uses augmented reality (AR) to gauge the size of objects. Itâ€™s not just a static image of a ruler â€“ itâ€™s a dynamic tool that interacts with the space around you.

### Step 1: Open the Measure app

Locate and tap the Measure app icon on your iPhone to open it.

The Measure app is pre-installed on most iPhones, so you wonâ€™t need to download anything new. Itâ€™s usually found in your Utilities folder or on your home screen if you use it frequently.

### Step 2: Follow the on-screen instructions

When you first open the Measure app, youâ€™ll be prompted with on-screen instructions to move your iPhone around.

This helps the app calibrate and understand the space around you. Itâ€™s a crucial step to ensure the measurements are as accurate as possible.

### Step 3: Point your iPhone camera at the object

Aim your iPhoneâ€™s camera at the starting point of the object you want to measure.

Make sure youâ€™re in a well-lit area and that the objectâ€™s edges are clear. The more visible the object is, the more accurate your measurement will be.

### Step 4: Tap the â€˜+â€™ button to start measuring

Press the â€˜+â€™ button on the screen to set the starting point for your measurement.

Youâ€™ll see a virtual white dot appear on the object, indicating where the measurement starts. Ensure this dot is precisely where you want to begin measuring.

### Step 5: Move your iPhone to the end point

Slowly move your iPhone to the end point of the object youâ€™re measuring, keeping the device steady.

The app will draw a virtual line as you move, showing the length being measured. Try to keep your movements smooth for the best results.

### Step 6: Tap the â€˜+â€™ button to finish measuring

Once youâ€™ve reached the end point, tap the â€˜+â€™ button again to set the final measurement.

Youâ€™ll then see the measured length displayed on the screen. If you need to measure another side of the object, just reposition your iPhone and repeat steps 4 through 6.

After you complete these steps, youâ€™ll have a precise measurement of the object in question. Whether youâ€™re sizing up a piece of furniture, checking the dimensions of a frame, or simply satisfying your curiosity, the Measure app on your iPhone is a surprisingly handy tool.

## Tips on How to Use Ruler on iPhone

• Make sure the object youâ€™re measuring is on a flat surface for the best results.
• If the app has trouble detecting the object, try moving closer or adjusting the lighting in the room.
• For smaller objects, you can use the Measure appâ€™s built-in level tool for added precision.
• Remember that the Measure app is best for approximate measurements â€“ for critical tasks, use a physical ruler or tape measure.
• You can take a photo of your measurement by tapping the shutter button, which is great for keeping a record.

### How accurate is the iPhone ruler?

The iPhoneâ€™s Measure app is quite accurate, but it should be used for approximate measurements rather than precision engineering.

### Can the Measure app measure height?

Yes, you can measure an objectâ€™s height by measuring from the base upwards.

### Does the Measure app work in the dark?

The Measure app requires good lighting to function correctly, so it may not work well in the dark.

### Can I measure the distance between two points on a map with the Measure app?

No, the Measure app is designed for measuring physical objects, not distances on a map.

### Can the Measure app measure angles?

The Measure app includes a level tool, which can be used to measure angles relative to the ground.

## Summary

1. Open the Measure app.
2. Follow the on-screen instructions to calibrate.
3. Aim the camera at the objectâ€™s starting point.
4. Tap the â€˜+â€™ button to start measuring.
5. Move your iPhone to the end point.
6. Tap the â€˜+â€™ button again to finish measuring.

## Conclusion

So, there you have it! Using the ruler on your iPhone is a piece of cake once you get the hang of it. Itâ€™s one of those nifty tricks that can save you time and hassle when a physical ruler isnâ€™t on hand. Whether youâ€™re a DIY aficionado, a student, or just someone who loves exploring the myriad of features their iPhone offers, the Measure appâ€™s ruler function is worth getting familiar with. And remember, while itâ€™s handy for quick measurements, itâ€™s not a replacement for professional measuring tools when precision is key. So, the next time you need to size something up, give your iPhone a chance to show off its measuring skills!
