Does an iPhone 16 Plus case fit the iPhone Air?
No, it won't fit.
Our supplier makes a separate case for each phone, cut to that phone's own size, camera, buttons and ports, and the two cases aren't the same shape. An iPhone 16 Plus case isn't made for the iPhone Air, and the difference is large enough that it won't sit properly or line up with the camera and buttons. Printed area of each case: iPhone 16 Plus 106 × 172 mm, iPhone Air 102 × 169 mm.
Two different cases

printed area 106 × 172 mm

Each case is cut for its own phone's camera, buttons and ports. Look at the camera cut-outs above: that's the part most likely to clash. Printed areas are from our supplier's specifications and include the sides of the case.

What happens if I use an iPhone 16 Plus case on the iPhone Air?
A case made for another phone can cover part of the camera, press or miss the buttons, leave gaps that let the phone slip out when dropped, and stop MagSafe accessories lining up. For proper protection, use a case made for the iPhone Air.
Do your iPhone Air cases work with MagSafe?
Yes. MagSafe magnets are built into every case, so chargers, wallets and car mounts snap on, and wireless charging works through the case.
