4 pt equals 5.3333 px.
Table of Contents
The conversion from points (pt) to pixels (px) depends on the screen resolution, where 1 point equals 1/72 of an inch and pixels are device-dependent. Assuming the standard 96 dpi (dots per inch), 1 pt converts to 1.3333 px. Thus, multiplying 4 pt by 1.3333 gives the pixel value.

Conversion Formula
The formula to convert points to pixels is based on the relationship between points, inches, and pixels. 1 point (pt) is defined as 1/72 inch. Screens usually display 96 pixels per inch (dpi). So, you multiply the points by the ratio of pixels per inch to points per inch:
Pixels = Points × (Pixels per inch / Points per inch)
Since pixels per inch is 96 and points per inch is 72:
Pixels = Points × (96 / 72) = Points × 1.3333
Example for 4 pt:
- 4 pt × 1.3333 = 5.3333 px
Conversion Example
- Convert 6 pt to px:
- Multiply 6 by 1.3333
- 6 × 1.3333 = 8 px
- So, 6 pt equals 8 px
- Convert 2.5 pt to px:
- 2.5 × 1.3333 = 3.3333 px
- Rounded to 3.3333 px
- Convert 10 pt to px:
- 10 × 1.3333 = 13.333 px
- Result is 13.333 px
- Convert 0 pt to px:
- 0 × 1.3333 = 0 px
- No size in pixels

Conversion Definitions
pt (point): A point is a unit of length used in typography and printing, equal to 1/72 of an inch. It defines the size of fonts and spacing in print design, offering a consistent measurement across different devices and printers. Points allow designers to maintain uniform appearance in printed text.
px (pixel): A pixel is the smallest unit of a digital image or display, representing a single point on a screen. Pixels size depends on screen resolution and density, varying between devices. Pixels are used in web design and digital graphics to control the layout and visual appearance precisely.
Conversion FAQs
Does the conversion from points to pixels change based on device?
Yes, because pixels depend on screen resolution or DPI (dots per inch), the exact px value of a pt can vary. The standard assumes 96 dpi, but high-density screens have more pixels per inch, altering the conversion. Points remain constant physically, while pixels adjust based on device.
Why is 1 pt equal to 1.3333 px in this conversion?
This is due to the relationship between points and pixels at 96 dpi. One point equals 1/72 inch, and one pixel equals 1/96 inch. So to convert, multiply points by 96/72 = 1.3333. This ratio makes text and graphics consistent across digital platforms assuming the standard dpi.
Can I use points instead of pixels in web design?
While CSS supports points, pixels are more common because they map directly to screen units. Points are more suited for print layouts. Using points in web design may lead to unpredictable results on different devices, because pixel density affects how points display on screens.
What happens if I use negative point values in conversion?
Negative points convert to negative pixels, representing negative size values. This has no physical meaning in most contexts but might be used in calculations or animations to indicate direction or inversion. Most practical uses avoid negative font sizes or dimensions.
Is the formula the same for converting px to pt?
The reverse conversion multiplies pixels by 72/96 (or 0.75). Since px to pt is inverse of pt to px, applying the reciprocal ratio gives the point value from pixels. This is useful when adjusting designs from digital units back to print measurements.
