Screen Size vs Phone Size

Many people mix up these two terms.

Screen size is the diagonal of the screen. It runs from one corner to the opposite corner.
Phone size is the whole body. It includes height, width, and thickness.

Here is a real example. The iPhone 8 Plus has a 5.5-inch screen. The iPhone 16 has a 6.1-inch screen. So the iPhone 16 should be bigger, right? Not quite. The iPhone 8 Plus is 158.4 mm tall. The iPhone 16 is only 147.6 mm tall.

Why? Old iPhones had thick bezels. A bezel is the empty border around the screen. New iPhones have thin bezels. So they fit a bigger screen in a smaller body. What matters more to you: a big screen or a small body?

Want a phone that is easy to hold? Pick a lighter and thinner one.

Which iPhones Are the Same Size?

Some iPhones look new but have the same size as older ones. This helps when you shop for cases or screen protectors.

Same size group	Models	Height x Width
Group 1	iPhone 12, 12 Pro, 13, 13 Pro, 14, 16e, 17e	146.7 x 71.5 mm
Group 2	iPhone 15 and 16	147.6 x 71.6 mm
Group 3	iPhone 12 Pro Max, 13 Pro Max, 14 Plus	160.8 x 78.1 mm
Group 4	iPhone XR and 11	150.9 x 75.7 mm
Group 5	iPhone 17 Pro and 18 Pro	150.0 x 71.9 mm
Group 6	iPhone 17 Pro Max and 18 Pro Max	163.4 x 78.0 mm

Is the Pro bigger than the regular model? Not always. The iPhone 15 Pro (146.6 x 70.6 mm) is slightly smaller than the iPhone 15. The 17 Pro is a little bigger than the 17.

Buying a case? Height and width may match, but thickness can differ. Camera and button spots can also change. So check the case maker’s list before you buy.

Older iPhone Sizes

Do you own an older iPhone? Or do you want to buy a used one? Here is how the old models compare.

Model	Screen	Height
iPhone 11	6.1″	150.9 mm (15.09 cm)
iPhone X	5.8″	143.6 mm (14.36 cm)
iPhone 8 Plus	5.5″	158.4 mm (15.84 cm)
iPhone 8	4.7″	138.4 mm (13.84 cm)
iphone 7	4.7″	138.3 mm (13.83 cm)
iPhone 6	4.7″	138.1 mm (13.81 cm)
iPhone 5	4.0″	123.8 mm (12.38 cm)
iPhone 4	3.5″	115.2 mm (11.52 cm)
Original iPhone	3.5″	115.0 mm (11.50 cm)

What do these numbers show?

The first iPhone had a 3.5-inch screen. That is about half the size of today’s biggest iPhone (6.9 inches).
Apple grew the screen step by step. It went from 3.5 to 4, then 4.7, then 5.5 inches.
The iPhone 8 Plus has a smaller screen than the iPhone 11. But it is 7.5 mm taller.

Quick tip: Buying a used iPhone? Check the height first. Old phones with big bezels feel larger than their screen size suggests.

Screen Resolution and Pixels

What is a pixel? It is a tiny dot on your screen. Think of a mosaic made of small tiles. More tiles make a sharper picture. Resolution tells you how many pixels the screen has. The first number is the long side. The second is the short side.

6.9″ screen (18 Pro Max, 17 Pro Max): 2868 x 1320 pixels
6.3″ screen (18 Pro, 17 Pro, 17): 2622 x 1206 pixels
6.1″ screen (17e): 2532 x 1170 pixels

All three screens have 460 ppi. PPI means pixels per inch. A higher number means a sharper screen. So a bigger iPhone does not look sharper. It just has more pixels to fill its larger screen. Why does this matter? Designers and app builders use these numbers to size their work.

Inches, mm and cm: Quick Conversion

Do shops list sizes in inches while charts use mm? Use these simple rules:

Inches to cm: Multiply by 2.54.
mm to cm: Divide by 10.
mm to inches: Divide by 25.4.

Real examples:

iPhone 16 height: 147.6 mm = 14.76 cm = 5.81 inches
iPhone 14 Plus height: 160.8 mm = 16.08 cm = 6.33 inches

How to measure your screen:

Turn the screen off. It is easier to see the edges.
Place a ruler on one corner of the glass.
Measure to the opposite corner. Skip the phone’s border.
Compare the number with the chart.

Tip: Your result may differ a little from the official size. That is normal.

Which iPhone Size Should You Choose?

Still not sure? Answer these four questions.

1. Do you use your phone with one hand?
Pick a narrow phone. The iPhone 17e is only 71.5 mm wide and weighs 169 g.

2. Do you watch lots of videos or play games?
Pick a big screen. The iPhone 18 Pro Max has a 6.9-inch display.

3. Is your pocket small?
Pick a thin phone. The iPhone Air is only 5.64 mm thick. It slips in easily.

4. Do you want long battery life?
Pick a Pro Max. The 18 Pro Max plays video for up to 45 hours. The 18 Pro lasts up to 36 hours.

Real-life example: Sara rides the bus every day. She holds a bag in one hand. She needs a phone she can use with the other. The iPhone 17e fits her best.

Try before you buy:

Visit a shop.
Hold the phone the way you normally do.
Try to reach the top corner with your thumb.
Put it in your pocket or bag.

Why are iPhones so big now? People watch more videos and play more games. Big phones also hold bigger batteries. Thin bezels let Apple fit more screen in the same body.
