Measuring things on the go used to be a challenge. People often needed a traditional ruler, tape measure, or some other tool to get accurate numbers. Today, thanks to digital measuring tools built into smartphones, you can easily measure everyday objects without carrying extra equipment. Both Apple and Samsung have introduced AR technology in smartphones that turns the camera into a powerful measuring tool. At the same time, third-party apps from the Google Play Store measurement apps and Apple’s App Store give you even more choices. In this guide, you’ll learn 4 ways to use your iPhone or Android phone as a ruler and how these methods can save time in daily life, home projects, or even interior design.
One of the best parts about using your phone as a ruler is that it doesn’t just help with small items like a pen or a notebook. With AR-based tools, you can measure entire pieces of furniture, door frames, or wall spaces. Imagine you’re moving into a new home and trying to check if your sofa fits in the living room. Instead of running to the store for a measuring tape, you can quickly point your phone’s camera and check the object dimensions. This convenience has made smartphone AR measurement apps a modern-day replacement for rulers and tapes.
4 ways to use your iPhone or Android phone as a ruler
Use the Ruler app by NixGame
The Ruler app by NixGame has become one of the most popular choices for those looking for a virtual ruler app that works on both iPhones and Android phones. It is simple to use and acts like a measurement tool app that allows you to place objects directly on the phone screen to measure them. This is especially handy for items like credit cards, coins, or small craft materials. Many users appreciate that it’s free and available from the Google Play Store measurement apps, making it easy to install whenever needed.
However, like any digital tool, it has limitations. You may need to use phone screen calibration for ruler accuracy to make sure measurements are correct. The app shines when used for quick checks, but for larger items, it is less effective compared to camera-based measuring tools. Still, for students, DIY enthusiasts, and anyone needing quick numbers, this app provides fast results without carrying an actual ruler.
Use iPhone as a ruler (Measure app)
If you own an iPhone, you don’t even need to download anything. Apple includes the Measure app (iPhone) as part of iOS. This tool is powered by augmented reality tools and uses your phone’s camera to measure not only the length of objects but also the area of rooms or furniture. To use it, simply open the app, point your camera at the item, and place digital points at the start and end. Within seconds, the iPhone as a ruler gives you numbers that are surprisingly accurate.
Interior designers, students, and homeowners often find this tool invaluable. For example, when placing new shelves or artwork, the iPhone as a ruler can quickly calculate whether the space is enough. This has become an everyday indoor measurement solution that replaces the need for physical tools. Just remember that while it’s highly reliable, measurement accuracy on mobile can sometimes vary depending on lighting or camera stability.
Use Quick Measure on Samsung phones
Samsung has developed its own tool called Quick Measure on Samsung phones, which is part of the AR Zone Samsung feature. Much like Apple’s Measure app, this feature relies on camera-based measuring and sensors to determine length, width, and even volume. The Samsung Quick Measure app is particularly helpful for furniture fitting and placement, making it an essential feature for anyone setting up a home or office.
This app is available on select Samsung models, especially those with advanced depth sensors. It offers faster and sometimes more detailed results compared to third-party apps. If you’re deciding between a phone vs measuring tape, Quick Measure can often hold its own in accuracy while being much more convenient.
Use the Ruler tool on the Edge panel (Samsung)
If you have ever been in a situation where you needed to measure something quickly but didn’t have a measuring tape, knowing 4 ways to use your iPhone or Android phone as a ruler can be a real lifesaver. Modern smartphones come with built-in tools and apps that allow you to measure objects accurately, whether it’s through augmented reality (AR) technology, a screen ruler app, or special features like Samsung’s Quick Measure and iPhone’s Measure app. These methods not only make your phone more versatile but also save time when measuring everyday items at home, school, or work.

The Measure app (iPhone) excels in versatility and is ideal for distance and area measurement. The Samsung Quick Measure app is powerful for AR-based measuring, especially in home renovation. Finally, the Edge Panel ruler Samsung tool is a quick and offline solution for everyday objects.
