If you’re looking about which iPhone has the largest screen, there are two answers, depending on whether you include Apple’s foldable model.

The iPhone Duo has the largest iPhone display at 7.6 inches when its inner screen is fully opened. For a traditional non-folding iPhone, the largest screen is 6.9 inches, found on the iPhone 18 Pro Max, iPhone 17 Pro Max, and iPhone 16 Pro Max.

Below is a complete list of iPhone models and their screen sizes, including current and older models.

Which iPhone Has the Largest Screen?

The iPhone Duo currently has the largest iPhone screen.

It has a 7.6-inch inner folding display when opened. It also has a 5.4-inch outer display for normal use when the phone is folded. Apple describes the inner display as a 7.6-inch Super Retina XDR folding display.

If you don’t want a foldable iPhone, the answer changes.

Largest non-folding iPhone

The largest traditional iPhone screen is 6.9 inches. The models with this screen size are:

• iPhone 18 Pro Max
• iPhone 17 Pro Max
• iPhone 16 Pro Max

Apple lists all three with a 6.9-inch diagonal display.

What Is the Largest iPhone Screen Size Without a Pro Max?

The iPhone Air has a 6.5-inch display, making it one of the largest current non-Pro Max options.

For comparison, the iPhone 16 Plus and iPhone 15 Plus have 6.7-inch displays, while the iPhone Air has a 6.5-inch display. Apple lists the iPhone Air’s display as a 6.5-inch diagonal all-screen OLED display.

What Is the Smallest iPhone Screen?

The smallest iPhone screen ever released is 3.5 inches.

The following models all had 3.5-inch displays:

• Original iPhone
• iPhone 3G
• iPhone 3GS
• iPhone 4
• iPhone 4s

Apple later moved to larger 4-inch displays with the iPhone 5, followed by 4.7-inch and 5.5-inch models.

The smallest modern full-screen iPhones were the iPhone 12 mini and iPhone 13 mini, both with 5.4-inch displays.

How iPhone Screen Sizes Have Changed

The iPhone has gone through a significant range of screen sizes since the original 3.5-inch model.

The major screen-size milestones include:

• 3.5 inches: Original iPhone through iPhone 4s
• 4.0 inches: iPhone 5, 5s and 5c
• 4.7 inches: iPhone 6 through several later SE models
• 5.5 inches: Plus models such as iPhone 6 Plus, 7 Plus and 8 Plus
• 5.8 inches: iPhone X, XS and 11 Pro
• 6.1 inches: Became one of Apple’s most common sizes
• 6.7 inches: Introduced with the iPhone 12 Pro Max and used by later Plus and Pro Max models
• 6.9 inches: Used by the Pro Max models beginning with the iPhone 16 Pro Max
• 7.6 inches: Introduced with the foldable iPhone Duo

This means the largest current iPhone display is more than twice the diagonal size of the original iPhone’s 3.5-inch screen.

Does a Larger Screen Mean a Larger iPhone?

Not necessarily.

Screen size is measured diagonally, rather than by the phone’s height or width. Two iPhones can have similar screen sizes but different physical dimensions because of their aspect ratios, bezels, and overall design.

For example, Apple’s 6.5-inch iPhone Air has a different physical design from older 6.5-inch models such as the iPhone 11 Pro Max and iPhone XS Max.

Also, Apple’s display measurements are based on a diagonal measurement. Because modern iPhone displays have rounded corners, the actual viewable area can be slightly smaller than the standard rectangular measurement.
