What the difference means for your site

Width: 384px vs 448px

Headings and buttons wrap differently: a line that fits in 448px can break onto two lines in 384px. Anything with a fixed width between the two makes the narrower screen scroll sideways (fix it).

Height: 832px vs 998px

On first load a page shows 712px on the Samsung Galaxy S25 Ultra and 852px on the Google Pixel 10 Pro XL, so “above the fold” differs by 140px.
