Questions

How do I compare iPhone sizes?

Put up to four models in the URL and the tool draws them together at true scale on one baseline, then lists every dimension underneath. iPhone 18 Pro against iPhone 18 Pro Max is a good place to start.

What's the biggest iPhone?

The iPhone 18 Pro Max is the biggest non-folding iPhone, with a 6.9-inch display and a body of 163.4 x 78 x 8.75 mm. The folding iPhone Duo (unfolded) is wider when open at 117.8 x 164.6 x 5.2 mm, with a 7.6-inch inner display.

What's the smallest iPhone available?

The iPhone 13 mini is the smallest modern iPhone, with a 5.4-inch display and a body of 131.5 x 64.2 x 7.65 mm.

Are iPhone dimensions in mm or inches?

Both. Every measurement is published in millimetres by default, and a millimetres / inches switch converts the whole page at once. Screen size is the exception: it is always quoted in inches, the way Apple quotes it.

Can I see actual size on my screen?

Yes. The drawing is true scale, and the caption states the exact pixels-per-millimetre it is using, so the relative size difference between two models is always right. Absolute size is right too on a screen whose pixel density matches your browser’s reported density.

How accurate is the comparison tool?

Height, width, depth, weight, display size and resolution come from Apple’s published specifications. Corner radii, camera-module footprints, button positions and colour values are our own estimates for procedural drawing, not Apple drawings.

What's the difference between screen size and phone size?

Screen size measures the display diagonal in inches; phone size is the physical body. The iPhone 18 Pro shows why they are not the same thing: a 6.3-inch display inside a body of only 150 x 71.9 x 8.75 mm, because the bezels around it are so narrow.

Will my old iPhone case fit the new model?

Rarely, and matching dimensions are not enough on their own. The iPhone 8 and the iPhone SE (3rd gen) are both 138.4 x 67.3 x 7.3 mm, yet a case for one does not guarantee a clean fit on the other, because the camera and button cut-outs differ. Buy a case made for your exact model.
