Lenovo Legion Tab Gen 3 VS OnePlus Pad 3

The most striking design difference between these two tablets is sheer scale. The Lenovo Legion Tab Gen 3 is a compact device at 208.54 × 129.46 mm and 350 g, making it closer in footprint to a large phone than a traditional tablet. The OnePlus Pad 3, by contrast, measures 289.6 × 209.7 mm and weighs 675 g — nearly twice as heavy. In practice, the Legion Tab is far easier to hold one-handed for extended gaming or media sessions, while the OnePlus Pad 3 demands two hands and feels more like a laptop replacement than a portable device.

Where the OnePlus Pad 3 partially compensates for its bulk is in thickness: at just 6 mm, it is notably slimmer than the Legion Tab's 7.8 mm. That thinness gives it a premium, svelte feel despite its larger frame, and helps it slide more easily into a bag. Neither device offers any water resistance, and both lack a detachable or backlit keyboard, so accessories are not a differentiator here. However, the OnePlus Pad 3 ships with a stylus included — a meaningful out-of-the-box bonus for note-taking or creative work that the Legion Tab simply does not offer.

Overall, the Legion Tab Gen 3 has a clear portability edge for users who prioritize a light, pocketable form factor. But if screen real estate, a slimmer profile, and a bundled stylus matter more, the OnePlus Pad 3 holds the advantage as a more capable desk- or lap-oriented device. The right choice depends squarely on whether portability or productivity surface area is the priority.

Screen size is where these two tablets diverge most dramatically. The OnePlus Pad 3 sports a massive 13.2″ IPS LCD versus the Legion Tab Gen 3's compact 8.8″ panel — a difference that fundamentally shapes how each device is used. The Pad 3's larger canvas is genuinely better suited for split-screen multitasking, document editing, and cinematic media consumption, while the Legion Tab's smaller footprint makes it a more focused, handheld-friendly display. Both panels share the same LCD IPS technology and identical 500 nits typical brightness, so neither holds an inherent advantage in panel quality or outdoor visibility.

Pixel density tells an interesting story. Despite its far higher raw resolution of 3392 x 2400 px, the OnePlus Pad 3 actually lands at a slightly lower 315 ppi than the Legion Tab's 343 ppi — because its pixels are spread across a much larger screen. In practice, both exceed the threshold where individual pixels become indistinguishable at normal viewing distances, so sharpness is not a real differentiator. More meaningful is the refresh rate: the Legion Tab's 165Hz panel (with matching touch sampling) gives it a tangible edge in gaming smoothness and input responsiveness over the Pad 3's 144Hz. For a device clearly positioned toward gaming, that higher cadence matters. The Pad 3 counters with Dolby Vision support, which enables better HDR tone mapping on compatible streaming content — a perk the Legion Tab entirely lacks.

On balance, neither display is strictly superior. The Legion Tab Gen 3 edges ahead for gaming thanks to its higher refresh rate and pixel density, while the OnePlus Pad 3 holds the advantage for media and productivity with its vastly larger screen and Dolby Vision certification. The best choice here is dictated by use case rather than raw display quality.
