Before purchasing your Noir Divine case, it’s important to make sure you select the correct MacBook model. Our premium laptop covers are designed with precision for four specific devices:
- MacBook Air 13"
- MacBook Pro 13"
- MacBook Air 15"
- MacBook Pro 14"
Because each model has its own unique shape and measurements, choosing the right fit ensures your new case will look seamless, feel secure, and protect your laptop flawlessly.
Here are two simple ways to check which size you need:
Option 1 — Check the Size on Your Mac
If you have the laptop in front of you, you can find the exact size in seconds.
How to check:
-
Click the Apple logo in the top-left corner of your screen.
-
Select About This Mac.
-
A window will open showing your MacBook information - including the screen size in inches (for example: MacBook Air 13-inch or MacBook Air 15-inch).

Option 2 — If you’re buying a gift (or don’t have access to the laptop)
When you want to surprise someone but don’t know their MacBook size, there’s an easy solution:
just check the model number on the bottom of their laptop.
How to check:
-
Flip the MacBook over.
-
Look for a small printed code beginning with the letter A.
(Example: A2681, A2338, A2779, etc.) -
This four-digit number tells you exactly which MacBook model it is.
Below is the table that shows which A-number matches which MacBook size.

Your MacBook deserves a premium case that fits flawlessly — not loosely, not tightly, but exactly right.
A precise fit ensures:
-
Scratch protection
-
Shock resistance
-
Better airflow & cooling
-
No slipping
-
A luxurious, seamless look
That’s why selecting the correct model is so important.
