So, you’re looking at the newest iPad Air and trying to figure out if it’ll actually fit in your bag—or if it's going to feel like you’re lugging around a cafeteria tray. Honestly, it's a valid concern. Ever since Apple decided to split the lineup into two distinct sizes, things got a little more complicated.
The short answer? It depends on which one you grab. You’ve got the 11-inch model and the 13-inch beast. But "11 inches" doesn't mean the device itself is 11 inches wide. That’s just the diagonal screen measurement.
Let's break down the physical reality of how big is iPad Air so you don't end up with a tablet that feels like a massive mistake.
The Tape Measure Truth: 11-inch vs. 13-inch
When we talk about the 11-inch iPad Air—which is currently in its M3 iteration as of early 2025—we’re looking at a height of 9.74 inches and a width of 7.02 inches. It’s incredibly thin, sitting at exactly 0.24 inches (or 6.1 mm). To put that in perspective, it’s about as thick as a few credit cards stacked together.
It weighs just about a pound. 1.02 pounds, to be exact.
Then you have the 13-inch model. This one is the "new" kid on the block that first showed up with the M2 chip and carried over into the 2025 M3 refresh. This thing is significantly larger. We’re talking 11.04 inches tall and 8.46 inches wide.
Interestingly, it’s the exact same thickness as the smaller one: 0.24 inches.
However, that extra screen real estate adds weight. It clocks in at 1.36 pounds. That might not sound like much of a jump, but hold both in a Best Buy for five minutes and your wrists will definitely feel the difference.
Real-World Footprint
If you’re trying to visualize this, the 11-inch model is roughly the size of a standard composition notebook. You know, the ones you used in high school. It fits on an airplane tray table with plenty of room left for a ginger ale and a tiny bag of pretzels.

The 13-inch model is basically the size of a standard sheet of A4 printer paper, but just a tiny bit shorter. If you put it in a backpack, it takes up the space of a 13-inch MacBook Air.
Screen Real Estate: Is it Actually 11 Inches?
Here is a little secret: the "11-inch" iPad Air isn't actually 11 inches.
If you look at the fine print on Apple’s spec sheets, the actual viewable area is 10.86 inches. Why do they do this? Marketing. "11-inch" sounds much cleaner than "10.86-inch."
The 13-inch model follows the same logic. The actual diagonal measurement is 12.9 inches. This is the same screen size that used to be exclusive to the iPad Pro for years. Now that it’s on the Air, it’s become the go-to for artists and students who need to see two apps side-by-side without squinting.
Pixel Density and Resolution
Both models have a pixel density of 264 pixels per inch (ppi).
- The 11-inch model gives you a 2360-by-1640 resolution.
- The 13-inch model bumps that up to 2732-by-2048.
Basically, everything looks equally sharp on both. The 13-inch just gives you more "stuff" on the screen. It’s great for Split View, but if you’re just watching Netflix in bed, it can feel a bit like you’re holding a TV over your face.
How Big Is iPad Air Compared to Previous Generations?
A lot of people are upgrading from the iPad Air 4 or 5. If that's you, the 11-inch M3 model is going to feel very familiar. Apple basically kept the chassis the same.
The dimensions for the Air 4, Air 5, and the 11-inch Air 6/7 (M2/M3) are virtually identical. This is great news because it means many older cases—like the Magic Keyboard—will still fit the newer 11-inch models.
But if you’re moving from an older 10.5-inch iPad Air 3 (the one with the Home button), the change is massive. Even though the device footprint is similar, the screen on the newer models goes almost edge-to-edge. It feels like a much bigger canvas because you aren't staring at those chunky "forehead and chin" bezels from 2019.

The Portability Paradox
Which one should you actually get?
If you’re a traveler, the 11-inch is the king. It fits in those small "personal item" crossbody bags. You can hold it with one hand for reading on the subway without feeling like you’re doing a forearm workout.
The 13-inch is a desk-first device. It’s for the person who wants a laptop replacement but likes the idea of a tablet. It’s incredible for drawing with the Apple Pencil Pro because you have room to rest your palm. But as a "couch tablet"? It’s kinda clumsy.
Why Weight Matters More Than You Think
- 11-inch (462 grams): Lightweight enough to hold for a two-hour movie.
- 13-inch (617 grams): Heavy enough that you'll likely want a stand or a case that props it up.
Adding a keyboard case changes the math too. A 13-inch iPad Air plus a Magic Keyboard weighs nearly 3 pounds. At that point, you’re carrying the same weight as a MacBook Pro.
Actionable Tips for Choosing Your Size
Don't just look at the numbers. Think about your daily routine.
- Check your bag: Measure the internal sleeve of your favorite backpack. Most "tech" bags are built for 13-inch laptops, meaning the 13-inch Air will fit, but it’ll be snug.
- Think about your "Handedness": If you plan to use the iPad while standing (taking notes at a construction site or in a hospital), get the 11-inch. The 13-inch is too top-heavy for long periods of one-handed use.
- Budget for the extras: A bigger screen means a more expensive Magic Keyboard and more expensive screen protectors. The "size" cost isn't just the $200 price jump between the tablets themselves.
- Multitasking needs: If you use Stage Manager or want to keep your email open while you write a document, the 11-inch will feel cramped. The 13-inch is the only one that truly feels like a "pro" multitasking machine.
If you’re still on the fence, go to a store and try to type on the on-screen keyboard. On the 11-inch, it’s manageable with thumbs. On the 13-inch, it's almost impossible unless you have giant hands. Most people find the 11-inch is the "sweet spot" for tablet things, while the 13-inch is the winner for "work" things.
