What size phone screen do I need?

Time for an upgrade? When choosing a new smartphone, one of the most important decisions you’ll make is screen size. From compact displays that are easy to use one-handed to larger screens built for streaming, gaming, and multitasking, the right size depends on how you use your phone day to day.

How are smartphone screens measured?

Screen size measurements for smartphones are calculated by measuring diagonally from the upper left-hand corner of the screen to the lower right-hand corner¹. These measurements are expressed in inches. Larger screen phones are typically said to be 6.5-inches or above, such as the innovative Galaxy Z Flip7 with its 6.9-inch unfolded display. The Samsung Galaxy S25 Ultra² also boasts an impressive 6.9 inch-display, but you can go even bigger with the Galaxy Z Fold7³ display when unfolded for immersive streaming and gaming.

Phone screen sizes

Phone screen sizes vary across different models. Depending on the length of your thumb and index finger, some phones will be more comfortable to hold and use. Different screen sizes also come with different functions. Smaller phone screens tend to be more compact and lightweight, while larger screen phone sizes allow more space for you to work on multiple applications at once. So, choosing the best size smartphone depends on how you plan to use your phone. We’ve put together some quick tips below to help you pick the best phone screen size for you.

Small mobile phones

Phone screen sizes that are smaller than 4.5 inches are usually considered small mobile phones. You should choose a small-sized phone if you want a compact smartphone for everyday tasks such as replying to messages, reading and browsing. Looking for the best of both? The Galaxy Z Flip7 is a small but mighty phone when folded, with a compact 3.4-inch cover display to quickly check notifications, weather alerts, and more. But, when it’s time to get things done, just flip it open to reveal a full-sized 6.9-inch smartphone screen.

Medium size phones

Medium size phones are ones between 4.5 and 6.5 inches, perfect for those who want a good balance between portability, quality specs and innovative features. Galaxy S25's 6.2-inch Dynamic AMOLED 2X screen is a great medium size mobile phone, providing bright and clear images both in daylight and at night.

Large screen phones

Smartphones with screen sizes larger than 6.5 inches are considered large screen phones. This is your best phone screen option if you are looking for a smartphone for multitasking, streaming, or playing graphic-intensive games. Looking for the largest Samsung Galaxy phone? Check out the sensational The Galaxy Z Fold7, which features not one, but two incredible screens. You’ve got a 6.5-inch cover display for all your day-to-day tasks on the front - but when it comes to the serious stuff, simply unfold to reveal a stunning 8-inch screen. That’s the same size as a small tablet! It’s optimised for getting everything done, all on one screen, at the same time.
