When exporting to PowerPoint (or Word), the size in Excel is preserved as well as the Width to Height ratio.
There are two potential issues with this behavior:
- The Width to height ratio in Excel changes with your display settings. For example: if you change the size of all Items from 100% to 125% (see picture below), the tables in Excel will look different. This means that exporting the same table on two different computers can yield a slightly different result. Similarly, when you update a document send to you by a colleague, you might observe differences.
- When you paste Excel tables as image in PowerPoint manually, the width to height ratio is preserved but the size is modified. The scale of this modification is dependent upon the resolution and is not documented by Microsoft. Because of this, UpSlide automatically scales the image to make it match the size in Excel. The only drawback is that the scale ratio displayed in PowerPoint is not intuitive (see picture below where the scale is 144% even if the the table has just been exported from Excel).
