Those specifications make it a relatively small, light option among the models compared here, but they cannot guarantee comfort for every hand. If you would rather turn pages with buttons than reach across a touchscreen, compare larger button-equipped readers such as Kobo Libra Colour.
How to judge whether an e-reader will work one-handed
There is no established weight or screen-size threshold that predicts comfortable one-handed reading. Screen diagonal, body dimensions and weight are useful ways to narrow the field; grip shape, thumb reach, fatigue and page-turn preference are personal. A case can also change both weight and grip. If possible, hold or weigh the device with the case you plan to use.

Start by deciding which tradeoff matters most: the smallest listed dimensions, physical page-turn buttons, a color screen, or the reading ecosystem you already use. Product specifications and comparison figures are not results from a controlled ergonomics study.
Compare the main models
| Model | Screen and weight | Useful distinction |
|---|---|---|
| Kobo Clara BW | 6 inches; 174 g; 112 × 160 × 9.2 mm (Kobo specifications) | Monochrome screen, touchscreen, adjustable ComfortLight PRO and IPX8 waterproofing |
| Kobo Clara Colour | 6-inch screen; Kobo rates it at 300 PPI for black-and-white content and 150 PPI for color (Kobo specifications) | Color illustrations and highlighting in a 6-inch form factor; touchscreen |
| Kobo Libra Colour | 7 inches; 199.5 g (TechRadar comparison) | Sculpted edge with physical page-turn buttons; orientation changes when flipped, according to Kobo |
| Kindle Paperwhite (2024) | 7 inches; 211 g (TechRadar comparison) | A 7-inch comparator for readers who prefer Amazon’s ebook ecosystem |
| BOOX Go 7 | 7 inches; 195 g (TechRadar comparison) | Page-turn buttons; TechRadar lists it as 4 g lighter than Libra Colour |
The screen diagonal does not describe the whole device or show how it fits your hand. Among the figures above, Clara BW is the only model with cited body dimensions. The 7-inch alternatives offer more screen area, but their listed weights are higher than Clara BW’s.

Choose between touchscreen and buttons
Clara BW and Clara Colour use touchscreens. If reaching across the screen to turn a page is awkward, Libra Colour’s physical buttons may suit your preferred motion. Kobo describes the buttons as being on a sculpted edge and says they reorient when you flip the reader. BOOX Go 7 is another 7-inch button-equipped option in the cited comparison.
Buttons do not make a device universally easier to hold: the reader still has to fit your grip, and both listed button-equipped options have 7-inch screens. Try the page-turn method as well as the grip if you can.

Decide whether color is worth the display tradeoff
Clara BW has a black-and-white Carta 1300 screen. Clara Colour keeps a 6-inch screen but adds color: Kobo specifies 300 PPI for black-and-white content and 150 PPI for color. Color can be useful for illustrated books, comics or color highlighting; for text-only reading, do not assume it is an upgrade without considering that difference in color resolution.

Account for lighting, water protection and battery claims
Kobo lists adjustable ComfortLight PRO and IPX8 waterproofing for Clara BW. Its stated battery life is up to 53 days based on 30 minutes of reading per day, front light at 10% brightness, and Wi-Fi and Bluetooth turned off. That is a manufacturer estimate under those specific conditions, not a general expectation for every reading routine.
Rank #3

Match the choice to your priorities
Choose Clara BW as the compactness-first starting point
Its listed 6-inch screen, 174 g weight and specified body dimensions make it the clearest fit here when small size and low listed weight matter most. It also has a monochrome display, front-light controls and waterproofing. The specifications support a compactness-based recommendation, not a promise about hand comfort.
Choose Clara Colour for color in a 6-inch reader
Consider it if color illustrations or highlighting matter more than having the highest-resolution color display. Kobo’s cited figures distinguish 300 PPI black-and-white content from 150 PPI color content.

Compare Libra Colour or BOOX Go 7 for buttons
These are 7-inch alternatives when physical page turns matter. Libra Colour weighs 199.5 g in TechRadar’s comparison; BOOX Go 7 is listed at 195 g. Their larger screen and button controls are a different tradeoff from Clara BW’s smaller listed size.

Check your market before buying
Prices and availability depend on country and can change, so verify them with the seller for your region. Confirm case compatibility with the exact model and generation: a cover adds weight and can change grip, and a listing for one Clara model should not be assumed to fit another.
For Kobo’s own model comparison, see its eReader comparison page. Kobo’s product specification pages are the source for the Clara models’ screen and feature details; TechRadar’s comparison supplies the cited weights for the 7-inch alternatives.
