How to Convert Pixel to Percent Formula Explained

If you want to convert pixel values into dpi manually, you can use the formula below. But before doing so, you must understand how this Formula is derived.

Firstly, understand the relationship between pixels, percentages & Parent Element’s Dimension.

As you know:

• Pixels(px) are an absolute unit of measurement.
• Percentage(%) is a relative unit in CSS.
• Parent Element’s Dimension(px) is the reference value against which you can calculate the percentage.

So, let’s derive the Formula by considering these terms.

A percentage is a fraction out of 100.

To express a pixel value as a percentage of the parent’s width, you need to determine what fraction of the parent’s width the pixel value represents. 

So, divide the pixel value by the parent’s width. It will become:

Fraction = Pixel Value (px) / Parent Width (px)

Now, multiply the fraction by 100 to convert it to a percentage. 

Pixels to Percentage Formula

Percentage (%) = ( Pixel Value (px) / Parent Width (px) ) * 100

Use Cases of Pixels to Percentage Converter

Following are some uses of this px to percentage converter that help you in website designing and development:

• Transforming Fixed-Width Pixel Layouts into Fluid, Responsive Designs
• Creating Elements that Scale Proportionally within Parent Containers for Responsive Behavior
• Building Flexible and Adaptable Grid Systems with Percentage-Based Columns
• Setting Responsive Spacing, Padding, and Margins that Adapt to Layout Size

Difference Between Pixels & Percentage

Pixels are absolute units with fixed Values and remain exactly how you specify. On the other hand, percentages are relative units. Its calculated Value will always be relative to something else, like its parent element.

Pixels are less inherently responsive, meaning layouts built primarily with pixels tend to be fixed-width. In contrast, percentages are intrinsically more responsive and fluid, and layouts built primarily with percentages are designed to be flexible.
