Does 1 CSS point amount to the same as 75% of a CSS Pixel?

Can anyone help clarify the relationship between CSS pixels and CSS points in modern web design? I've come across information stating that one CSS point is equivalent to 3/4 of a pixel. Is this accurate? Also, is it true that we can disregard the old notion that 1pt equals 1/72 of an inch due to variations in resolution and monitor sizes?

If I need to convert CSS points to pixels, would a formula similar to this be appropriate: Xpt/75*100 = Ypx?

Similarly, if I need to convert pixels to points, could the formula look something like this: Xpx -25% = Ypt?

Answer №1

The pixel density of your screen and the resolution will determine the value of 1 point, also known as dpi or ppi. Typically, 1pt is equivalent to 1/72 of an inch.

Given that most monitors have a dpi of 96, 1pt would be equal to 72 / 96 = 0.75 pixels.
