The MacBook Pro 16″ (2021–2026) is 18px wider and 10px taller in CSS pixels. Small enough that most layouts behave the same, but fixed widths between 1710 and 1728px will spill on the narrower one.

What the difference means for your site

Width: 1710px vs 1728px

Headings and buttons wrap differently: a line that fits in 1728px can break onto two lines in 1710px. Anything with a fixed width between the two makes the narrower screen scroll sideways (fix it).

Height: 1107px vs 1117px

On first load a page shows 982px on the MacBook Air 15″ (M2–M5) and 993px on the MacBook Pro 16″ (2021–2026), so “above the fold” differs by 11px.
