The Dynamic Island Is Eating Your X Header (Here's the Fix)

The Dynamic Island arrived with iPhone 14 Pro and quietly became the most consequential change to Twitter (X) header design in years. Combined with the status bar, it carves a 50- to 60-pixel slice out of the top of your banner — on every Pro-tier iPhone in your audience's pocket.

If you designed your header in Figma, exported at 1500×500, and uploaded directly: the top of your image is being eaten by chrome on a meaningful percentage of your audience right now. This guide explains exactly what's happening and how to fix it.

What the Dynamic Island actually does

On iPhone 16 Pro and Pro Max, the system reserves a horizontal band at the top of every screen for the status bar (battery, time, network) and the pill-shaped Dynamic Island. X — and most other platforms — render your banner edge-to-edge, which means that chrome sits on top of your banner image, not above it.

Anything you placed in the top 50–60 pixels of your 1500×500 source image is partially or fully hidden under that chrome on iPhone 16 Pro / Pro Max. On smaller iPhones with notches, the geometry is different but the principle is the same.

Why your laptop preview misses this

Desktop X has no Dynamic Island. The same image renders without any top-edge overlay. So when you preview your header on the machine you designed it on, it looks fine — even though half your audience is seeing the cropped version.

This is the most common reason creators ship broken headers: the tool they design in (Canva, Figma, Photoshop) and the tool they preview on (their own laptop) are both blind to mobile chrome.

Three rules for designing around the Dynamic Island

1. Treat the top 60 pixels as off-limits. Don't put text, logos, or any content you care about in that band. Background art, gradients, and decorative elements are fine.

2. Center your headline. If your banner has a tagline or CTA, vertically center it. The middle 60% of the banner is the safest real estate on every device.

3. Leave breathing room. Don't pack the banner edge-to-edge. Generous padding around your headline and logo gives you margin against unexpected chrome.

How to verify your fix

Once you've redesigned, you have two real options for verification:

• Check on a real iPhone 16 Pro/Pro Max. Upload your banner to a test X account and view it on the device. This works but takes minutes per iteration.
• Run a header preview audit. Better Header renders your image on every iPhone profile and tells you exactly which areas are clipped, with pixel coordinates to fix. About 90 seconds per audit.

What to take away

• The Dynamic Island and status bar carve 50–60 pixels out of the top of your X banner on iPhone 16 Pro / Pro Max.
• Your laptop doesn't show this. Mobile is the source of truth.
• Treat the top 60 pixels of your banner as decorative-only. Move real content to the central band.
• Audit on real device profiles before publishing. Don't ship a banner you haven't seen on iPhone.
