CSS px are the units media queries see. Visible heights subtract the status bar and the Safari on iOS bars as set in our device profiles; real bar heights vary with settings and scrolling. The release year is that of the first model with each screen.
What this means for your layout
How the width difference affects your layout
The iPhone 15 is 3 CSS px wider (393 vs 390, 1% more). No common breakpoint falls between 390 and 393 px, so with typical media queries both get the same layout and the extra 3 pixels only stretch fluid columns, text lines and images.
In a 2-column card grid with 16 px page padding and 16 px gaps, each card is 172 px wide on the iPhone 15 and 171 px on the iPhone 14. Check that buttons, prices and long words still fit in the narrower one.
Pixel density and image sizes
Both draw each CSS pixel with 3 × 3 device pixels, so text and icons are equally sharp. A full-width image (sizes="100vw") needs about 1170 px on the iPhone 14 and 1179 px on the iPhone 15 to look sharp.
With a srcset such as 640w, 828w, 1080w, 1290w, 1440w, 1640w, 2048w, the browser would normally pick the 1290w file on the iPhone 14 and the same one on the iPhone 15.
Above 2× most people can't see much difference in photos, so capping photo candidates around twice the CSS width saves bytes on both. Keep SVG for icons and logos: they stay sharp at any ratio.
How much fits above the fold
On first load about 667 px of the page is visible on the iPhone 14 and 662 px on the iPhone 15: 5 px less (1%) on the iPhone 15. The iPhone 14 has the shorter screen but shows more, because its bars take less room (177 vs 190 px). That's less than one line of body text, so in practice both show the same first screen.
In landscape
Turned sideways, the iPhone 14 is 844 px wide and the iPhone 15 852 px. The visible height drops to about 340 and 343 px, so a 64 px sticky header covers 19% and 19% of the screen — under the 25% at which MobileCheck flags fixed bars covering the page.
Same browser engine
Both are Apple devices, so both render with WebKit, the engine behind Safari. Engine quirks are the same; the differences above come from size alone. Chrome DevTools only emulates the size and still draws with Chromium, so check Apple devices in a WebKit browser — see how to test on an iPhone.

Frequently asked questions
Is the iPhone 14 screen bigger than the iPhone 15?
In CSS pixels, which decide how much of a page fits, the iPhone 15 is larger: 393 × 852 against 390 × 844. The iPhone 15 has more physical pixels (1179 × 2556), which makes it sharper rather than roomier.
Do I need different CSS for the iPhone 14 and the iPhone 15?
Usually not. No common breakpoint falls between their widths (390 and 393 px), so a fluid layout gets the same rules on both and only stretches by 3 px.
How much of a web page is visible on the iPhone 14 vs the iPhone 15?
About 390 × 667 CSS px on the iPhone 14 and 393 × 662 on the iPhone 15 when a page first opens in portrait, after the status bar and Safari on iOS's bars. Bar heights are our device profiles' estimates.
