iOS 26 is rolling out for everyone today and it’s a chunky download. On the phone I used to check it – an iPhone 14 Pro Max – the update shows 6.17 GB. Your number may be a little higher or lower depending on model, region, and what’s already on your device.
Why it’s big
This is a full annual release with the new Liquid Glass look across Lock Screen, Home Screen, and system controls, plus broader Apple Intelligence features, Live Translation, and updates to core apps like Phone and Messages. Big visual assets and new on-device models add up.
Size varies by device
Two people can see different sizes even on the same day. Factors include:

Quick tips before you update
- Make some extra space beyond the download for unpacking.
- Back up to iCloud or a computer.
- Plug in and use reliable Wi-Fi.
- If you’d rather not wait around, choose Update Tonight and let it install while the phone is locked and charging.
Bottom line: expect roughly a 6 GB download for iOS 26. If your iPhone shows a different figure, that’s normal for a major release.
I’m 72 and not sure how to add Liquid Glass on my iPhone 12pro
Hi! You don’t have to install anything, it’s part of the new interface style. To see it, make sure your iPhone 12 Pro is updated to iOS 26. You’ll notice the “Liquid Glass” look in widgets, Control Center, and parts of the Lock Screen. You can customize how it looks by going to Settings → Wallpaper & Display → Appearance → Liquid Glass and choosing your preferred color or depth.
