How Do I Know Which Size Case Will Fit My Kindle?

Trying to figure out which size case will fit your Kindle? The answer depends on what device you have, as you can then shop for your case by the model and its generation.

This guide breaks it down nice and simple so you can be confident you’re choosing a case that’ll fit.

How to Find Your Kindle Model and Generation

There are a few ways to track this down:

• Settings on your Kindle — open Settings > Device Options > Device Info on your Kindle. Your model number will be listed there (it'll look something like SA568B or M2L3EK). 

• The back of your device — the ‘Model No.’ is printed in small text on the back at the bottom.

• Your Amazon account — head to Manage Your Content and Devices, click on your Kindle, and the model and generation will be listed under device details.

• The original listing page where you purchased your device — the generation is usually listed there too.

Once you have it, you can match it against a Kindle Compatibility Guide or use the table further down.

Kindle Case Sizes at a Glance

Does Kindle Screen Size = Kindle Case Size?

Not quite, and it's worth being clear on this. 

Cases are built to fit the full physical dimensions of the device, not just the display. Even Kindles that share a screen size can have very different case requirements due to varying bezels, thickness, and body changes across generations.

That said, screen size is still useful. Each Kindle generation has its own screen size, so knowing yours helps you confirm you're distinguishing generations correctly. 

For example, the Kindle Paperwhite 11th Gen (2021) has a 6.8" screen; the 12th Gen (2024) has a 7" screen. Same model name, different generation, different case. If you know your screen size, it points you to the right generation, and the right case.

Casely organizes Kindle cases by screen size for exactly this reason. Once you've identified your model and generation — or confirmed your screen size — you can filter straight to the right case and shop from there.

Shop Kindle Cases by Size

The average Kindle user reads 35 eBooks per year. That's a lot of hours with your device in your hand, which makes the case worth thinking about.

A good Kindle case needs to be designed specifically for your model so the cutouts line up with your charging port, power button, and ambient light sensor. Get that wrong, and the case is no good.

Casely’s Kindle cases are designed with precise cutouts for these features and made to perfectly fit the most popular Kindle models and generations. 

Here's where to find yours.

Frequently Asked Questions

Do All Kindle Cases Fit All Kindles?

No. Kindle cases are model-specific, not universal. Each generation has its own physical dimensions, so a case built for one model won't fit another correctly, even if the screen sizes look similar. Always check your model and generation before buying to make sure the fit is right.

How Do I Know What Case to Get for My Kindle?

Identify your Kindle model and generation first. So, go to Settings > Device Options > Device Info. You can also look at the small print on the back of your device, or your Amazon account under Manage Your Content and Devices. Once you know your model and generation, shop cases built specifically for it.

What If I Can't Find My Kindle Model Number?

Check your Amazon account under Manage Your Content and Devices. Then, click on your Kindle, and the model and generation will be listed under device details. Alternatively, the original listing page where you purchased your device usually has the generation listed too.

What Is the Best Case for a Kindle?

The best Kindle case is model-specific, genuinely protective, and one you'll actually want to carry. Look for a design that lines up with your ports and buttons, uses durable materials, and adds a comfort feature or two, like a hand strap for long reading sessions. If it looks great doing all of the above, even better.

Find Your Fit, Then Find Your Favorite
