The Nintendo Switch 2 announcement trailer immediately reveals a significant size increase compared to its predecessor. As the original Joy-Con detach, the tablet section visibly expands, showcasing a substantial upgrade. This suggests a departure from Nintendo's historically pocket-friendly handhelds, embracing the larger portable device market alongside competitors like the Steam Deck and iPad.
While Nintendo hasn't released official dimensions, we can offer a reasonable estimate based on the trailer and a recent leak. At CES 2025, we handled a Switch 2 mock-up by peripheral maker Genki. Although its accuracy was unconfirmed then, Nintendo's trailer shows a remarkably similar design, suggesting our CES measurements are quite accurate.
Here's our estimated Switch 2 size breakdown:

Nintendo Switch 2 Screen Size
We estimate 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 screen. The Switch Lite's 5.5-inch screen is 45% smaller diagonally and 111% smaller in area; the Switch OLED's 7-inch screen is 14% smaller diagonally and 30% smaller in area. Even against the Steam Deck's 7-inch (original) and 7.4-inch (OLED) screens, the Switch 2 boasts an 8% and 11% larger area respectively.

Nintendo Switch 2 Overall Console Size
The larger screen results in a larger console. Our CES measurements of the Genki mock-up, corroborated by trailer analysis, suggest a Switch 2 size of 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 12% smaller than the Steam Deck (298mm x 117mm). Depth appears similar to the original Switch.

Nintendo Switch 2 Joy-Con Size
The trailer suggests Joy-Con width remains similar, but height increases. Our estimations point to 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, we estimate the screen unit at 200mm long and 115mm tall, approximately 31% larger than the original. This allows for roughly 11mm side bezels and 8mm top/bottom bezels.
These measurements are estimations. While based on the Genki mock-up and trailer analysis, they may differ from Nintendo's official figures. However, we anticipate a console roughly 25% larger than the original.
