At imcasefl, we often hear from customers who accidentally purchase the wrong Kindle case. The most common confusion comes from Kindle Paperwhite 11th (2021) and Kindle 11th Gen (2022 basic model). Since both are called “11th generation,” many people assume they are the same—but in fact, they are quite different in size and features.
This guide will help you understand the key differences and, most importantly, how to check your device code before ordering a case.
1. Overview of Both Models
-
Kindle Paperwhite 11th (2021): Fifth generation of the Paperwhite line, featuring a larger display and advanced features.
-
Kindle 11th Gen (2022, Basic Kindle): The eleventh generation of the entry-level Kindle series, smaller and more lightweight.
2. Key Differences
| Feature | Kindle Paperwhite 11th | Kindle 11th Gen (Basic) | What It Means for You |
|---|---|---|---|
| Display Size | 6.8” E-Ink, 300 ppi | 6.0” E-Ink, 300 ppi | Paperwhite shows more text and feels better for long reading; Basic is smaller and ultra-portable. |
| Front Light | Adjustable warm light (color temperature), more LEDs | Standard front light, fewer LEDs | Paperwhite offers a more comfortable night-reading experience. |
| Waterproof | IPX8 waterproof | Not waterproof | Safer for bath, poolside, or beach reading. |
| Storage Options | 8 GB / 16 GB (standard), 32 GB (Signature Edition) | 16 GB | Great for manga or PDFs; Basic is enough for regular eBooks. |
| Weight & Size | Slightly larger and heavier | Smaller and lighter | Basic is easier to carry around. |
| Battery Life | Up to 10 weeks (typical use) | Slightly shorter than Paperwhite | Both last far longer than tablets/phones. |
| Price | Mid-to-high range | Entry-level, more affordable | Choose based on your budget and reading needs. |
3. Device Codes (Most Important!)
The device code is the most reliable way to identify your Kindle model and ensure you buy the correct case.
You can find it on your Kindle:
Settings > Device Options > Device Info > Device Model/Code
-
Kindle Paperwhite 11th (2021, 6.8”)
-
Device Codes: PQ94WIF / PQ94WIF (Intl.) / G001PX
-
Usually shown as “Kindle Paperwhite 11th Gen”
-
-
Kindle 11th Gen (2022, 6.0” Basic)
-
Device Codes: B09SWWLDYZ / LDC-1132 / G001PX
-
Usually shown as “Kindle 11th Gen”
-
👉 Even though both are “11th,” the cases are not interchangeable. Paperwhite cases are larger and will not fit the smaller Basic Kindle.
4. How to Quickly Check Your Model
-
Open Settings on your Kindle.
-
Go to Device Options.
-
Tap Device Info.
-
Check the Device Code/Model and match it with the list above.
5. Conclusion
-
If your Kindle has a 6.8” display, supports warm light and waterproofing, you own a Kindle Paperwhite 11th.
-
If it has a 6.0” display, with no warm light adjustment, and feels more compact, it’s the Kindle 11th Gen (Basic).
-
Always double-check your device code before purchasing a case to avoid compatibility issues.
