330 pt equals 440 pixels (px).
To convert points (pt) to pixels (px), you multiply the point value by 1.3333, because 1 pt is equal to 1/72 of an inch and 1 px is defined as 1/96 of an inch, so the conversion factor is 96/72 = 1.3333. Multiplying 330 pt by 1.3333 gives 440 px.

Conversion Formula
The formula to convert points (pt) to pixels (px) is:
px = pt × (96 / 72)
This works because points and pixels are both units to measure length on screens or print but have different base definitions. One point is 1/72 of an inch, while one pixel is 1/96 of an inch. So, to convert points to pixels, you multiply the point value by the ratio of pixels per inch to points per inch, which is 96 divided by 72.
Example calculation for 330 pt:
- Start with 330 pt
- Multiply by 96 to convert inches to pixels: 330 × 96 = 31680
- Divide by 72 to convert points to inches: 31680 ÷ 72 = 440 px
Conversion Example
- Convert 150 pt to px:
- Multiply 150 by 96: 150 × 96 = 14400
- Divide 14400 by 72: 14400 ÷ 72 = 200 px
- Therefore, 150 pt = 200 px
- Convert 75 pt to px:
- 75 × 96 = 7200
- 7200 ÷ 72 = 100 px
- So, 75 pt equals 100 px
- Convert 500 pt to px:
- 500 × 96 = 48000
- 48000 ÷ 72 = 666.6667 px
- This means 500 pt is approximately 666.6667 px
- Convert 25 pt to px:
- 25 × 96 = 2400
- 2400 ÷ 72 = 33.3333 px
- Therefore, 25 pt equals about 33.3333 px

Conversion Definitions
pt (point): A point is a physical unit of measure used in typography and print, equal to 1/72 of an inch. It primarily defines font sizes and spacing in printed materials. Though it originated for print, points are used on screen for consistency in text size across devices.
px (pixel): A pixel is the basic unit of digital images and displays, representing one dot on a screen. It lacks a fixed physical size because it depends on the screen’s resolution and density, but typically it’s 1/96 inch in CSS standards for consistent layout rendering.
Conversion FAQs
Why is the conversion factor 96/72 between pt and px?
The 96 and 72 numbers come from screen and print standards. Points are based on 72 points per inch, a print measurement. Pixels are usually based on 96 pixels per inch, a screen measurement. So, converting requires multiplying pt by 96/72 to adjust the different unit scales.
Does converting 330 pt to px change on different devices?
Yes, the actual pixel size on screen can differ because device pixel density varies. The formula assumes a standard 96 DPI screen. High-DPI or retina devices will display pixels differently, sometimes scaling content for clarity, so physical size may vary despite the conversion.
Can I use the pt to px conversion for images?
Using pt to px conversion for images isn’t always accurate because images are measured in pixels, and their size depends on resolution and screen density. Points are for text and print. For images, pixels or other absolute units are preferred to ensure proper display size.
How precise is the conversion from points to pixels?
The conversion is mathematically precise using the 96/72 ratio, but actual display size can differ due to device variations, zoom levels, or browser settings. So, while the number is exact, the rendered size might not be perfectly consistent across environments.
Is it better to use pt or px for web font sizes?
Pixels are often preferred on the web because they provide more control and consistency across devices. Points are more common in print or desktop publishing. However, modern CSS supports both, and selecting depends on the design goals and target platforms.
