For example, your embed code will look similar to:
<iframe frameborder="0" noresize="noresize" src="https://www.symbaloo.com/embed/home603" name="_symFrame" width="740px" height="600px"></iframe>
To change the size, change the numbers next to "width=" and "height="
Making the numbers larger will make the webmix larger, and vice versa.
Note: If your embedded webmix is being cut off and tiles are not being shown, you may need to take some additional steps. These may include, but are not limited to: removing a sidebar and changing the layout of your blog. If you have resized your webmix, and your webmix is still cut off, please contact Support.
