You can attach images at any size and change the display size in Confluence. Thus, you can use the original image capture which provides the best resolution with the least loss of data.
To resize an image:
- In the page you want to change, click Edit.
- Select the image you want to resize. The image properties panel appears. Choose one of the following resizing methods:
- Enter the desired width in pixels; the height changes proportionally.
- Click one of the size buttons to use the preset small, medium, or large sizes.
For thumbnails, consider setting the width to 120 pixels. (The reader can click the thumbnail to expand it.) For icons, consider 20 pixels.
Keep in mind the needs of your audience. Some readers may be able to open a browser window 13 inches to view the entire width of a very large image, but some might not. It depends on monitor size and screen resolution. Wider images make scrolling necessary and may cause the page to be displayed improperly so that lines no longer wrap.
The following table provides suggested pixel widths, calculated based on 72 pixels per inch:
| Image Width in Inches | Width in Pixels |
|---|---|
| 13 | 936 |
| 12 | 864 |
| 11 | 792 |
| 10 | 720 |
| 9 | 648 |
| 8 | 576 |
Tip
If the image is not rendered properly in the browser, it will be necessary to resize in a tool, either to the exact dimensions or to a percentage of the original size. If the image was imported from Microsoft Word, removing the exact dimensions from the import may solve the problem. If the image then becomes too large, resize the image to a smaller size.
