How big is a 17.3-inch laptop screen? The gaming and workstation size, with dimensions and PPI
17.3 inches is the size you pick when the laptop is your only machine and you want desktop-class screen area in a single panel you can occasionally move. Heavy enough that you'll feel it in any backpack, big enough that multiple windows fit comfortably side by side. For daily commuting, a 16-inch 16:10 gives similar productivity workspace at roughly two-thirds the weight.
A 17.3-inch 16:9 laptop screen measures 15.07 inches wide by 8.48 inches tall, giving you about 127.8 square inches of display area. It's the largest mainstream laptop diagonal still in production, used almost exclusively on gaming laptops (ASUS ROG Strix, MSI Raider, Alienware m17) and mobile workstations (Dell Precision 7770, HP ZBook 17). The 16:9 aspect ratio matches games and video natively, which is why it dominates this class. Big, heavy, expensive, and intended to replace a desktop rather than share a backpack with one.

How this is calculated
In metric, 38.3 cm wide by 21.5 cm tall, roughly 825 cm². At the typical 1920×1080 resolution on a 17.3-inch panel you get about 127 PPI, which is fine for gaming and media but visibly soft for text work compared to a 15.6-inch 1080p panel at 141 PPI. Many 17.3-inch gaming laptops now ship 2560×1440 (170 PPI) or 3840×2160 (255 PPI) panels to address that. The 16:9 ratio trades vertical workspace for media compatibility, which on a 17.3-inch gaming laptop is the right trade. Chassis weight typically runs 3.0-3.6 kg, which is enough that most owners treat it as a portable desktop rather than a daily-carry laptop.
Verdict
17.3 inches is the size you pick when the laptop is your only machine and you want desktop-class screen area in a single panel you can occasionally move. Heavy enough that you'll feel it in any backpack, big enough that multiple windows fit comfortably side by side. For daily commuting, a 16-inch 16:10 gives similar productivity workspace at roughly two-thirds the weight.
