When choosing a screen size, see how close your size is to the ideal 16×9 or 4×3.

When producing video content, to ensure that the content is correctly scaled, does not blur, and remains undistorted, it is important to follow this rule:

1px on the screen = 1pt at 72 DPI/PPI

If your workspace allows you to set the DPI/PPI, by specifying 72, you can work with points as pixels. Consequently, when the content is displayed on the screen, there will be no scaling, and the image will remain sharp.

Let’s Understand Why

First, let’s understand the difference between px and pt:

• Pixels (px): The smallest unit of a digital image, representing a single point in a raster image.
• Points (pt): A unit of measurement used in typography, where 1 point equals 1/72 of an inch.

Conversion Formula

The conversion between pixels (px) and points (pt) depends on the resolution of the device, measured in PPI (Pixels Per Inch) or DPI (Dots Per Inch).

DPI (Dots Per Inch): Typically used in printing to describe the number of dots of ink per inch. It affects the clarity and detail of printed images.

PPI (Pixels Per Inch): Indicates the number of pixels per inch on the screen. A higher PPI value means more pixels per inch, leading to finer detail and sharper images.

The general formula for conversion:

px = pt × (PPI / 72)

Conversely

pt = px × (72 / PPI)​
