A laptop usually sits 14 to 24 in (36 to 61 cm) from your eyes. The table shows how much of your view a 13.3 inch screen fills at each distance. It feels wide at 14 in36 cm, ideal at 16 to 20 in41 to 51 cm and small in view at 22 to 24 in56 to 61 cm.
Which resolution suits a 13.3 inch laptop?
Higher resolution looks sharper but makes text smaller, so you need display scaling. At 13.3 inches, 1920 × 1200 gives 170 PPI and 2880 × 1800 gives 255 PPI. The table shows the Windows scaling each needs.
Sit farther away than the last column and you will not see single pixels. See every resolution in the chart.
At this size, 2880 × 1800 hides single pixels at every laptop distance. 1920 × 1200 hides them from about 20 in51 cm and 2560 × 1600 from about 15 in38 cm. At 275% scaling, 2880 × 1800 draws everything nearly three times as big, so its extra pixels go to sharpness, not space.
None of them runs at 100%, as text would be too small to read at 18 in46 cm.

How we measure
Screen width = diagonal x a / sqrt(a^2 + b^2) and height = diagonal x b / sqrt(a^2 + b^2) for an a:b screen. Viewing angle = 2 x arctan(half the screen width / distance). Pixel visibility uses 1 arcminute, the limit of 20/20 vision.
