What Size MacBook Air Sleeve Do I Need?

Before delving into sleeve sizes, it's crucial to understand the MacBook Air models and their dimensions. This is key to purchasing the correct sleeve to protect it.

MacBook Air Models and Their Sizes

13-inch MacBook Air

The 13-inch is loved for it compact design and sleek lines. Measuring 11.97 x 8.36 inches, the 13-inch MacBook Air is the smaller of the two models. Its slender profile and lightweight design make it an ideal choice for professionals and students on the go.

15-inch MacBook Air

The 15-inch is revered for its sleek design and ultra-thin profile. With dimensions of 13.3 x 9.4 inches, it offers a generous display while remaining remarkably lightweight. However, its thin build can make it more susceptible to damage, especially during transport.

Each Air model's unique dimensions necessitate size-specific Mac Air sleeves for several reasons.

Secure Fit

MacBook Air Sleeves: Precision-Fit Protection Since 1998

Here's the challenge most MacBook Air owners face: you invest $1,000+ in Apple's thinnest, lightest laptop, then struggle to find a sleeve that actually fits and protects properly.
