The Nintendo Switch 2 announcement trailer immediately reveals a significant size increase compared to its predecessor. As the original Joy-Cons detach, the tablet section visibly expands, hinting at a departure from Nintendo's traditionally compact handhelds and a move towards larger portable devices like the Steam Deck and iPad.
While official dimensions remain undisclosed, a recent leak offers clues. A Switch 2 mock-up at CES 2025, remarkably similar to the trailer's depiction, provided a basis for estimation.

Nintendo Switch 2 Screen Size
Our estimations suggest an **8-inch screen** (diagonal measurement, excluding bezels), aligning with earlier 2024 rumors. This translates to approximately **177mm wide and 99mm tall**. This represents a nearly 30% diagonal increase and a 66% larger area compared to the original Switch's 6.2-inch display. The Switch Lite's 5.5-inch screen is dwarfed by the Switch 2's 45% larger diagonal and 111% larger area. Even the Switch OLED's 7-inch display is noticeably smaller, with the Switch 2 boasting a 14% larger diagonal and 30% larger area.
In the context of current handheld competition, the Steam Deck's 7-inch (original) and 7.4-inch (OLED) displays are larger than previous Switch models. However, the Switch 2's 8-inch screen still surpasses even the largest Steam Deck screen, offering an 8% larger diagonal and 11% larger area.

Nintendo Switch 2 Overall Console Size
The larger screen necessitates a larger console. Measurements from the CES mock-up, corroborated by trailer analysis, suggest the Switch 2 measures approximately **265mm long and 115mm tall**. This is roughly **25% larger** than the original Switch (239mm x 102mm), 61% larger than the Switch Lite (208mm x 91mm), and about 12% smaller than the Steam Deck (298mm x 117mm). Depth appears comparable to the original Switch.

Nintendo Switch 2 Joy-Con Size
The trailer indicates slightly taller, but similarly wide, Joy-Cons. Our estimations suggest dimensions of approximately **32mm wide and 115mm tall**, a 13% increase over the originals.
Nintendo Switch 2 Screen Unit Size
Subtracting Joy-Con dimensions from the overall console size estimates the screen unit at approximately **200mm long and 115mm tall**, a **31% increase** over the original. This size accommodates the 8-inch screen with estimated bezels of 11mm on the sides and 8mm on the top and bottom.
It's crucial to remember these are estimations. While the Genki mock-up suggests accuracy, official dimensions may differ. However, we anticipate a console roughly 25% larger than the original Switch.
