3.5 pt is equal to 4.6667 px.
The conversion from points (pt) to pixels (px) depends on the screen resolution, commonly 96 pixels per inch. Since 1 point equals 1/72 of an inch, the conversion formula applies this ratio to calculate pixels from points.

Conversion Formula
The formula to convert points to pixels is:
pixels = points × (96 ÷ 72)
This works because 1 point equals 1/72 of an inch and most screens display 96 pixels per inch. Multiplying points by 96/72 converts the physical measurement in inches to pixels.
Example calculation for 3.5 pt:
- 3.5 pt × 96 ÷ 72
- = 3.5 × 1.3333
- = 4.6667 px
Conversion Example
- Convert 5 pt to px:
- 5 × 96 ÷ 72
- = 5 × 1.3333
- = 6.6667 px
- Convert 10 pt to px:
- 10 × 96 ÷ 72
- = 10 × 1.3333
- = 13.3333 px
- Convert 2.25 pt to px:
- 2.25 × 96 ÷ 72
- = 2.25 × 1.3333
- = 3.0000 px
- Convert 7.75 pt to px:
- 7.75 × 96 ÷ 72
- = 7.75 × 1.3333
- = 10.3333 px

Conversion Definitions
pt (point): A unit of measurement used in typography and printing equal to 1/72 of an inch. Points are used to specify font size, line spacing, and other elements in print media. It provides a physical measurement to ensure consistency across devices with different screen densities.
px (pixel): A pixel is the smallest unit of a digital image or display. In web and screen design, pixels measure visual elements on screen, based on screen resolution, usually 96 pixels per inch. Pixel sizes may vary on devices but are the standard for digital layouts and graphics.
Conversion FAQs
Does the 3.5 pt to px conversion change with different screen resolutions?
Yes, the conversion depends on the screen’s pixel density. The common standard assumes 96 pixels per inch, but screens with higher or lower DPI will show different pixel sizes for the same point value. So 3.5 pt may not always equal 4.6667 px on every device.
Why is the conversion factor 96/72 rather than a simple ratio?
The number 72 comes from points being 1/72 inch, while 96 comes from typical screen DPI. Multiplying by 96/72 converts the physical size in points to pixels considering screen resolution. Without this factor, the size would be inaccurate for screens.
Can negative point values be converted to pixels?
Technically yes, negative point values can convert to pixels mathematically, but in practical terms, negative sizes are not meaningful for display or print. The formula treats negative points as negative lengths, so the conversion follows the same ratio.
Why do some applications use different values to convert points to pixels?
Applications might use varying DPI settings or rounding methods, affecting the conversion. Some software targets print resolution (higher DPI), others screen resolution, so 3.5 pt could convert slightly differently depending on context and target device.
Is the pixel value always a decimal when converting from points?
Not necessarily. Since points and pixels use different units and typical DPI is 96, many conversions result in decimals. However, depending on the value and rounding, some conversions might produce whole numbers, but decimals are common.
