Apple’s upcoming flagship smartphone, the i Phone 18 Pro Max, retains the exact physical footprint of its predecessor despite significant internal changes. The device measures 163.4 millimeters in height, 78 millimeters in width, and 8.75 millimeters in depth. These dimensions are identical to the current i Phone 17 Pro Max. However, the new model introduces a noticeable increase in mass for users holding the device.
The primary difference between the two generations lies in their weight. Apple confirms that the i Phone 18 Pro Max tips the scales at 249 grams. This represents a 16-gram increase over the i Phone 17 Pro Max, which weighed 233 grams. While sixteen grams may seem minor on paper, the cumulative effect makes this the heaviest non-folding i Phone ever released by the company. The additional mass likely stems from upgraded internal components or battery enhancements required to support advanced features.
The added weight does not translate to a thicker chassis. Apple maintained the same 8.75-millimeter thickness, suggesting that the extra mass comes from denser materials or larger internal hardware rather than a bulkier exterior design. This approach allows Apple to keep the phone slim while accommodating more powerful technology inside. Users who have handled the previous model will notice the difference immediately upon picking up the new device. The shift reflects a broader trend in smartphone engineering where performance gains often require physical trade-offs.
For most consumers, the 16-gram difference might be negligible during brief interactions. However, for those who use their phones extensively throughout the day, the increased weight could impact comfort levels. Holding a 249-gram device for extended periods requires more hand strength compared to lighter alternatives. This development positions the i Phone 18 Pro Max as a premium device focused on maximum performance, potentially sacrificing some ergonomic ease for capability.
Is the i Phone 18 Pro Max physically larger than the i Phone 17 Pro Max? No, the external dimensions remain unchanged at 163.4mm x 78mm x 8.75mm. The only physical difference is the internal weight distribution.
How much heavier is the new model exactly? The i Phone 18 Pro Max weighs 249 grams, which is 16 grams heavier than the 233-gram i Phone 17 Pro Max.
Does this make it the heaviest i Phone ever? Yes, among non-folding models, the i Phone 18 Pro Max is currently the heaviest i Phone released by Apple.
