Understanding thickness

Thickness is a numeric spec measured in mm. On this metric, lower values are generally better — smaller, lighter, thinner, or less demanding usually translates to a more comfortable or more efficient product. When comparing two products, focus on the percentage gap rather than the raw delta: a 200-unit lead means something very different at the low end of the range than at the high end. Pay attention to the unit, too — manufacturers sometimes quote peak or burst figures that are not sustained in real-world use. Cross-check the published number against independent measurements where possible, especially for performance and battery claims. Finally, remember that a single spec rarely tells the whole story; the Mars Score weighs thickness together with the rest of the spec sheet so one outlier doesn't distort the verdict.

This matchupXiaomi 16 Ultra's 9.2mm is roughly 8% more than Pixel 9's 8.5mm (a 0.7mm gap). Lower is better here, so Pixel 9 takes the lead in real use.
