300 dpi corresponds to 300 pixels per inch. So, if you have an image with a resolution of 300 dpi, it means there are 300 pixels lined up in every inch of the image.
The dpi (dots per inch) value tells how many pixels are packed into one inch of a digital or printed image. Therefore, converting dpi to pixels depends on the physical size you want to measure in inches, because dpi alone only describes density, not total pixels.

Conversion Formula
To convert dpi to pixels, you need to multiply the dpi value by the physical measurement length in inches. The formula is:
Pixels = dpi × Inches
This works because dpi measures how many dots (pixels) fit into one inch. So, if your image width is 5 inches and dpi is 300, then the total pixels across the width are 300 × 5 = 1500 pixels.
Without knowing the inches, dpi alone cannot give total pixels. For 300 dpi at 1 inch, total pixels = 300 × 1 = 300 pixels.
Conversion Example
- Example: 150 dpi over 4 inches
- First, take dpi value: 150
- Multiply by image width in inches: 150 × 4
- Result is 600 pixels across the width
- Example: 72 dpi over 8.5 inches
- Start with dpi: 72
- Multiply by 8.5 inches: 72 × 8.5
- Resulting pixels = 612 pixels
- Example: 200 dpi over 3.2 inches
- Take dpi: 200
- Multiply by 3.2: 200 × 3.2
- Get 640 pixels
- Example: 96 dpi over 5 inches
- Dpi is 96
- Multiply by 5 inches: 96 × 5
- Pixels equal 480

Conversion Definitions
DPI: DPI, or dots per inch, is a measurement of printing or display resolution that indicates how many individual dots or pixels fit within one inch. It is used to describe the density of pixels in printed images or displays, affecting image sharpness and clarity.
Pixels: Pixels are the smallest discrete elements of an image shown on digital screens or printed media. Each pixel contains color and brightness information, and many pixels combined create a full image. Pixel count determines image resolution and detail level.
Conversion FAQs
Can dpi alone tell me how many pixels an image contains?
Dpi describes density, not total pixels. Without knowing the physical size in inches, dpi can’t provide the total pixel count. You must multiply dpi by the image’s width or height in inches to get pixel dimensions.
Why does printing at 300 dpi result in sharper images?
Higher dpi means more dots packed in every inch, producing finer details and smoother edges. 300 dpi is considered high quality for print, making images appear crisp compared to lower dpi like 72.
Is dpi relevant for digital screens?
Screens use pixels directly and have pixel density measured in PPI (pixels per inch), similar to dpi but not identical. While dpi matters for print, digital images depend more on pixel dimensions and screen resolution.
What happens if I set dpi incorrectly when printing?
Setting dpi too low causes pixelation, where individual pixels become visible, reducing image clarity. Too high dpi increases file size without noticeable visual improvement, so balance is needed.
Can I convert pixels back to dpi?
Yes, if you know the physical size in inches. Divide the total pixels by inches to get dpi. For example, 1200 pixels over 4 inches gives 300 dpi (1200 ÷ 4 = 300).
