When buying a new iPad case or keyboard cover, one of the most important steps is making sure it fits your device. A case that’s too tight won’t snap on properly, while one that’s too loose leaves your iPad unprotected. Measuring your iPad size and knowing the exact model ensures you get the right accessory without the frustration of returns. 

This guide walks you through everything you need to know: how to check your model number, measure dimensions, understand thickness, and what to do if you already bought the wrong size.

The easiest way to determine iPad size is by checking the model number.

• Go to Settings > General > About.
• Look for the field labeled Model Number.
• The number usually starts with an “A” (e.g., A2316).

Once you have it, match it against Apple’s official list of iPad models and screen sizes. This is the most reliable way to know which cases and accessories will fit your device.

If you don’t have the model number handy, you can still check manually:

• Use a ruler or caliper to measure your iPad’s height and width in millimeters.
• Compare with Apple’s published specifications online.
• Don’t forget thickness — some iPads differ by as little as 0.5mm, which is enough to affect fit.

For example, the iPad Air and iPad Pro 11" look nearly identical in shape, but their dimensions differ slightly. A precise measurement ensures the case will lock securely.

When browsing online stores, always check:

• The compatible model numbers listed in the description.
• The dimensions mentioned in the product details.
• Extra features such as pencil holders, stands, or keyboard support.

High-quality cases not only protect but also expand what your iPad can do. Some advanced options, like keyboard cases with extra ports and trackpads, allow your iPad to function more like a laptop. This is especially useful for students and professionals who often need external storage, quick file transfers, or larger screen presentations.

If you already purchased the wrong size, here’s what you can do:

• Check the return policy: Most sellers allow free returns within 30 days.
• Reconfirm your model number before buying a replacement.
• Consider multi-functional cases if you’re upgrading soon. They often support broader iPad ranges and come with detachable or adjustable parts.

In many cases, simply knowing your iPad model number is enough. Manufacturers design accessories specifically for certain models, and their product descriptions typically state compatibility clearly. 

That said, if your iPad is older or you’re buying from a third-party seller, double-checking dimensions and thickness can save time and hassle.

Q: Is measuring necessary if I already know my model number? 

A: Usually not. Model number confirmation is enough. 

Q: What if my iPad is slightly thicker than the listed case dimensions? 

A: Even a 0.5mm difference can matter. It’s safer to buy the exact size match. 

Q: Can a case support multiple iPad models? 

A: Yes, some flexible designs cover multiple models in the same size category.

Measuring your iPad is a small step that makes a big difference when buying accessories. Once you know your exact model and dimensions, you can explore cases that not only protect but also boost productivity — like those with built-in keyboards, extra ports, or adjustable stands.
