What the difference means for your site

Width: 1512px vs 1728px

Headings and buttons wrap differently: a line that fits in 1728px can break onto two lines in 1512px. Anything with a fixed width between the two makes the narrower screen scroll sideways (fix it).

Height: 982px vs 1117px

On first load a page shows 858px on the MacBook Pro 14″ (2021–2026) and 993px on the MacBook Pro 16″ (2021–2026), so “above the fold” differs by 135px.
