Using the Transform tool

To resize an image in Paint Tool SAI, you can use the Transform tool. This tool is used to scale and rotate images and can be activated by pressing Command-T.

Once the Transform tool is activated, you can resize the image from every side. While dragging the image, remember to hold the Shift button to maintain the same proportions. You can also hold Shift and Alt to resize the image without moving it, essentially sizing it from the middle.

Keep dragging the image until it reaches your desired size. Once you're done, press Enter to save the changes.

In addition to the Transform tool, Paint Tool SAI also offers the Scale and Rotate tools, which have similar functions to Transform. The Free Distort tool allows you to change the perspective and proportions of the selected area.

Holding Shift while resizing

Holding the Shift key while resizing an image in Paint Tool SAI allows you to maintain the aspect ratio of the original image. This means that the image will be resized proportionally, preventing any distortion in the height or width of the image.

To resize an image in Paint Tool SAI, you can use the Transform tool or the Change Size option. When using the Transform tool, you can activate it by pressing Ctrl + T, and then resize the image by dragging any side of the image. It is important to note that you should hold the Shift button while dragging the image to maintain the aspect ratio and avoid changing the proportions of the image.

Additionally, when using the Change Size option, you can specify the width and height in the pop-up window. Holding the Shift key while inputting the new dimensions ensures that the aspect ratio is maintained. This allows you to resize the image proportionally without distorting its original shape.

By holding Shift while resizing, you can ensure that the image is enlarged or reduced uniformly. This feature is particularly useful when you want to maintain the original composition and perspective of the image while changing its size.

It is worth noting that holding Shift and Alt together while resizing in Paint Tool SAI will result in resizing without moving. This means that the image will be resized from the middle, keeping the centre point of the image fixed. This additional keyboard shortcut provides more control over the resizing process, allowing for precise adjustments while maintaining the original aspect ratio.

  • In the pop-up window, enter your desired width and height for the image. You can specify the dimensions in pixels or percentages.
  • While keeping the Shift and Alt keys pressed, click and drag one of the corners of the image. You will notice that the image resizes from the center, maintaining its original aspect ratio.
  • Once you have achieved your desired size, release the mouse button, and then release the Shift and Alt keys.
  • Click "OK" to apply the changes. Your image will now be resized according to the new dimensions.

It is important to note that resizing an image can affect its quality and resolution. If you are resizing a small image to make it larger, it may become pixelated or blurry. Similarly, if you are reducing the size of a high-resolution image, you may lose some detail and sharpness. To mitigate these issues, you can use the Change Resolution option in Paint Tool SAI to adjust the image's resolution separately from its dimensions.
