Kobo Clara Colour vs Libra Colour: Which Case Fits

By the CaseBlossom team · November 2026

The short answer: the two families are different sizes, so a Clara case and a Libra case are cut differently and are not interchangeable. The Clara family — Clara Colour, Clara BW and the older Clara 2E — is Kobo's 6-inch reader; the Libra family — Libra Colour and Libra 2 — is the 7-inch model with page-turn buttons along one edge. Because the size and shape differ, you choose your exact Kobo model first and the case is made for it. Both families are covered across our illustrated designs in three styles — Built-In Strap Case, Regular Clear Case and Detachable Back Clear Case — with a free name or initials and a proof emailed before we print. Reading one-handed? Pick the strap style. Want to show the device itself? Pick a clear back. Not sure which Kobo is on your nightstand? Our Kobo identification guide settles it in under a minute.

The two Kobo families at a glance

• Clara family — 6 inches: Clara Colour, Clara BW and the earlier Clara 2E. One hand-sized slab, no page buttons.
• Libra family — 7 inches: Libra Colour and Libra 2. A larger screen plus physical page-turn buttons on one edge, so the body is asymmetric.

You can see both labeled on our model pages: Kobo Clara Colour 6" (N367) and Kobo Libra Colour 7" (N428).

Same designs, different cuts

Every illustrated design we make for Kobo comes in both families — the artwork is the same, but the case is cut for the model you select at checkout. A case made for the 6-inch Clara will not fit the 7-inch Libra, and the other way round, so the model choice always comes first. If you are deciding between the two readers themselves, think about how you read: the Clara suits a compact, pocketable setup, while the Libra's bigger screen and page buttons suit long two-handed sessions. For the case question specifically, the answer is simply: match the case to the reader you own.

Case styles available for Kobo

Kobo cases come in three styles, and the built-in strap works the same way as on our Kindle cases — a loop on the back cover your hand slips through:

• Built-In Strap Case — the pick for reading in bed or one-handed; the After Dark design shows it in the full Kobo option list.
• Regular Clear Case — a clear cover that lets the device show through, with nothing on the outside.
• Detachable Back Clear Case — a clear back piece that comes off, for readers who switch between bare device and case.

If you are still weighing up whether a case is worth it at all, do you need a case for your Kobo walks through the honest pros and cons.

How to tell which one you have

The fastest check is the model number: the 6-inch Clara Colour carries an N367-type model number, the 7-inch Libra Colour an N428-type. Both are printed on the device's settings screen and on the original packaging. If the numbers are long gone, which Kobo do I have goes through the visual checks — screen size, page buttons, home button placement — one by one.

How ordering works

Pick your exact Kobo model, pick a design — illustrated, or upload your own artwork — and add a name or initials for free. We email a proof before anything is printed; nothing is made until you approve it. The full range lives in the Kobo collection.

Frequently asked questions

Can a Clara case fit a Libra, or the other way round?

No. The Clara family is 6 inches and the Libra family is 7 inches with a different body shape, so the cases are cut per model and are not interchangeable. Order for the exact model you own.

Which Kobo models do your cases support?

Both Kobo families we list at checkout: Kobo Clara Colour, Clara 2E and Clara BW as one 6-inch option group, and Kobo Libra Colour and Libra 2 as the 7-inch option group.

Can I add a name or initials to a Kobo case?

Yes. A name or initials is free on every style, and you approve a proof before we print.
