Before going to step 5, let’s learn more about resize settings:

How it works: Paint offers two ways to resize the image. The first is the option of assigning a percentage or the second one is resize by pixel.

  • Resize by percentage: If you choose the option percentage, the default value is 100%. In addition, it offers the option of setting the size at the horizontal and vertical levels. In other words, if you set the value to 50, then the image will be halved. Conversely, if you set it to 200, then the image will be doubled in size.
  • Resize by Pixels: In this option, you can set the image file size image’s width and height by pixels. Consequently, if the number is increased, then the image will be larger. Conversely, by reducing the number, then the image will be smaller. That was another way to reduce or increase the image size by pixels.
  • Maintain aspect ratio: There is an option “maintain aspect ratio”. If you keep this option turn ON then you don’t need to put both (height & width) value. You just need to put a single value and another value will set automatically according to its aspect ratio so that the image doesn’t get stretched. If you require custom width and height, then you can turn off this option.

Step 5: Select the option Pixels. Make sure the checkbox “maintain aspect ratio” option is checked.

Step 6: Go to the horizontal field and remove the current value from there and put a new value as you want. As you can see, the vertical field value (Height) has been set automatically according to its aspect ratio. After setting the size, click on the OK button to get the effect. For example, we require to this image’s width size as 600 pixels, so I have set it to 600 pixels.
