How To Adjust and Change The DPI Resolution In MS Paint Tool

As a graphic designer with over 10 years of experience using MS Paint and other image editing software, I often get asked how to adjust the dots per inch (DPI) resolution in MS Paint. The DPI determines how clear and sharp an image looks when printed, so it’s important to set it appropriately based on your needs.

What is DPI and Why Does it Matter?

DPI stands for dots per inch. It refers to the output resolution of an image or document when printed. The higher the DPI, the more dots are squeezed into every inch, resulting in a sharper and more detailed print.

Here are some key things to know about DPI:

  • Print uses DPI while screens use PPI (pixels per inch): Printers print tiny dots to make up images, hence the relevance of DPI for print output. Screens display images using pixels instead of dots.
  • Standard DPI for print is 300: For most print projects, a DPI of 300 is recommended for sharp results. Some images can get away with lower DPI like 200, but 300 is best.
  • Higher DPI is better, to a limit: More DPI gives more dots and detail, but extremely high DPI wastes resources. 600 DPI is overkill for most prints.
  • Resampling changes DPI: You can adjust an image’s DPI by resampling it in a software like MS Paint. This scales the image to have more or fewer dots per inch.

Checking the Current DPI in MS Paint

When editing images in MS Paint, it’s important to know the current DPI so you can adjust it if needed. Here are the steps:

  1. Open your image file in MS Paint.
  2. Click the “Image” menu at the top.
  3. Select “Attributes” from the drop-down menu. This opens the Attributes window.
  4. Look at the “Resolution” field. This shows the horizontal and vertical DPI of your image.

For example, it may show “96 x 96 dpi”. This means the image has a resolution of 96 dots per inch horizontally and 96 dots per inch vertically.

Changing DPI Resolution in MS Paint

To change the resolution of an image in MS Paint:

  1. Follow the steps above to open the Attributes window and check current DPI.
  2. In the Resolution field, enter your desired DPI values. For best print quality, enter “300 x 300 dpi”.
  3. Click OK to close the window.
  4. Important: You must now resample the image for changes to take effect. Go to the Image menu > Resize.
  5. In the resize dialog, enter the current pixel dimensions of your image. This resamples the image at the new DPI.
  6. Click OK. The DPI is now updated to your chosen resolution! Check Attributes to confirm.

Note: Resampling changes the total size and pixels of your image. But it’s needed to properly integrate the DPI adjustment.

Tips for Setting the Right DPI

When changing DPI in MS Paint, keep these tips in mind:

  • Check final output: Print vs web? What printer? Set DPI accordingly.
  • Upsize for print: If resampling for print, upsize the dimensions to retain clarity.
  • Don’t exceed native resolution: Only increase DPI up to the native capability of the image source.
  • Maintain proportions: Use equal horizontal and vertical DPI to avoid distortion.
  • Use high-res source: Begin with the highest resolution image possible for best resampled results.

Alternative DPI Adjustment Methods

In addition to using MS Paint’s resize dialog to resample and change DPI, here are two other approaches:

Use MS Paint’s Zoom Feature

  1. Open your image and go to View > Zoom.
  2. Manually enter your desired DPI multiplied by the width or height.
  3. For example, enter “300 x 2000” for a 2000px wide image resized to 300 DPI.
  4. Go to Image > Attributes to confirm new resolution.

This quick zoom method avoids resampling, retaining original pixel dimensions.

Use Online DPI Converters

  1. Upload your image to a free online DPI converter tool.
  2. Enter your target DPI.
  3. Download the resampled image with adjusted resolution.

Handy for batch processing multiple images.
