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 Flip5 with its 6.7-inch main display. The Samsung Galaxy S24 Ultra² boasts an impressive 6.8 inch-display, or go even bigger with the Galaxy Z Fold5 7.6-inch³ Infinity Flex 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 Flip5 is a small but mighty phone when folded, measuring in at under 3.5-inches, it also has a useful 3.4-inch cover display. When it’s time to get things done, flip it open to reveal a full-sized 6.7-inch smartphone.

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 some innovative features. The Galaxy S24’s 6.2-inch FHD+ 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? That will be the sensational Galaxy Z Fold5 which features not one, but two incredible screens. You’ve got a 6.2-inch cover display for all your day-to-day tasks on the front and when it comes to the serious stuff simply unfold to reveal a stunning 7.6-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.

What can your thumbs actually reach?

When trying out a new phone, a great tip is to swipe your thumb across the phone screen from left to right in a curved arched. This way, you can work out what size phone screen works for you. For a comfortable fit you should be able to reach to approximately the middle of the screen or more.

Do you use your phone with two hands?

Think about how you type on your phone; do you use one hand or two? Large phone screens will probably feel more comfortable if you use two hands, whereas a smartphone with a small phone screen will be less of a stretch for one-hand typers. Can’t decide? Get the best of both worlds with the dual screen on Galaxy Z Fold5.

If you intend to use your Samsung smartphone for streaming TV shows & films or playing games, opt for phones with large screens (6.5 inches or larger).

Choose a bigger phone screen if:

• You use your phone for streaming, gaming and reading
• You work on your phone
• You have previously been using a large screen phone

Choose a smaller phone screen if:

• You don’t use your phone for gaming or work purposes
• You only want to type & browse using one hand
• You want a phone that can fit comfortably inside your pocket

If you usually use your phone with one hand, get a smartphone with a screen that’s between 4.5 and 6.5 inches like the 6.2-inch Galaxy S24 or 6.4-inch Galaxy A54 5G.
