Apple doesn't make it easy to compare sizes across generations. Specs are buried in product pages, numbers listed without context. This tool fixes that — every iPhone from the 11 through the 18 Pro Max and the foldable iPhone Duo, scaled to real-world proportions, sortable by any dimension. The Duo is drawn folded (pocket size); open dimensions are in the table below.
The question we built this for: will my current case still fit the new model? Or: is the Duo actually pocketable compared with a Pro Max? Numbers alone don't answer that. Visual scale does. See also the iPhone 18 Pro vs 17 Pro comparison.

iPhone Duo is listed folded and open. The visual chart above uses the folded (pocket) size. All measurements in millimeters (mm).
iPhone 13 mini at 131.5mm × 64.2mm × 7.65mm. The iPhone Duo is shorter folded (117.8mm) but 84.1mm wide.
iPhone 18 Pro Max at 163.4mm × 78.0mm × 8.75mm
iPhone 17 Air at 5.6mm thickness
iPhone Duo folded at 11.3mm. Slab Pro models: 8.75mm.
4.7" (iPhone SE) to 7.6" inner (iPhone Duo). Largest slab: 6.9" Pro Max.
Same 150.0 × 71.9 × 8.75mm footprint. 18 Pro is 5g heavier.
Based on physical dimensions, the iPhone 13 mini is one of the smallest recent models, with a height of 131.5mm. While the iPhone SE has a slightly larger physical height (138.4mm), the mini offers the smallest overall footprint for a modern, full-screen iPhone.
The Pro Max and Plus models often share nearly identical or very similar physical dimensions (Height and Width), as they both feature the large 6.7-inch or 6.9-inch display size. However, Pro models, such as the iPhone 15 Pro Max, are typically slightly thicker due to larger camera modules and internal components, which also makes them heavier.
The smallest iPhone in the 2026 lineup among slab phones is still the base iPhone 17 at 149.6mm tall. The foldable iPhone Duo is shorter folded (117.8mm) but much wider at 84.1mm — it is not a compact slab phone.
The largest slab iPhone in the 2026 lineup is the iPhone 18 Pro Max. It measures 163.4mm high and 78.0mm wide with a 6.9-inch display — the same footprint as the 17 Pro Max, at 249g. The iPhone Duo opens to a larger 7.6-inch inner screen.
Folded, the iPhone Duo is the thickest at 11.3mm. Among slab phones, the iPhone 17 Pro, 18 Pro, and both Pro Max models are 8.75mm thick. That extra depth is the camera stack and battery.
The thinnest model is the iPhone 17 Air at just 5.64mm. The Duo unfolds to 5.2mm but is 11.3mm folded. Among earlier models, the iPhone 12 and 13 Pro Max were 7.4mm.
While this tool focuses on physical dimensions (H × W × T), weight is generally correlated with size and material. The smallest and thinnest models, like the iPhone 13 mini or the iPhone 17 Air, are typically the lightest. The iPhone Duo is the heaviest at 254g. For a ranked list, see the weight comparison.
The standard iPhone 17 is slightly larger than the iPhone 16. The iPhone 17 is approximately 2.0mm taller and 0.15mm thicker than the iPhone 16. Both models feature the new 6.3-inch screen size (up from the traditional 6.1-inch display of the 14 and 15 generations).
The most important dimensions are Height (H), Width (W), and Thickness (T), all measured in millimeters (mm). Height determines how tall the phone is, Width relates to grip comfort, and Thickness impacts pocket-ability and overall hand feel. Our comparison tool visually scales the H and W for direct size comparison.
This tool focuses on iPhone models from the 11 series onward, which represents the modern design language with notches or Dynamic Island. Earlier models like the iPhone X, XS, and XR are not included, but we cover all major variants including mini, standard, Pro, Pro Max, Plus, SE, and the foldable iPhone Duo.
All dimensions are based on official specifications from Apple. iPhone 18 Pro, 18 Pro Max, and Duo figures are from Apple's September 9, 2026 event. We update this table when official specifications change.
