技术问询：13英寸MacBook Air屏幕的实际长宽尺寸（已知对角线13.3英寸）

Hey there! Let's break down the physical screen dimensions you're asking about for the 13.3-inch MacBook Air.

Most modern models (including the M1 and M2 iterations) use a 16:10 aspect ratio for their displays. From Apple's official specs, the actual physical screen measurements are:

• Width: ~11.04 inches (28.05 centimeters)
• Height: ~7.74 inches (19.65 centimeters)

If you want to double-check the math, you can use the Pythagorean theorem with the 16:10 ratio and 13.3-inch diagonal:
Let width = 16x, height = 10x. Then:
(16x)² + (10x)² = 13.3²
Solving for x gives you the base multiplier, and scaling back confirms the approximate dimensions listed above.

Even older 13.3-inch MacBook Air models (pre-2018) stick with the same 16:10 aspect ratio, so their screen sizes are nearly identical—you can rely on the numbers above for those too.
