# How does mso-width-percent get calculated?

• ### Question

• Hi all;

This question also holds for mso-height-percent, mso-left-percent, & mso-top-percent. But I figure they work the same way so getting one answered will be sufficient.

The definition for mso-width-percent is:

`Word uses this property to specify the width of the shape as a percentage of the layout object defined by the mso-width-relative property; its value is expressed as an integer between 10 and 10,000, inclusive, where each unit is a tenth of a percent.`

And for mso-width-relative it's:

`Word uses this property to specify the layout object referred to by the mso-width-percent property; its allowed values are margin, page, left-margin-area, right-margin-area, inner-margin-area, and outer-margin-area, with page being the default.`

Assuming mso-width-percent:1000 (ie 100%), then I'm assuming mso-width-relative:page means make it as wide as the page and mso-width-relative:margin means make it as wide as the are between the margins. Is that correct?

And then for left-margin-area and right-margin-area, make it as wide as from the paper edge to the margin edge?

And what is the measure for inner-margin-area, and outer-margin-area?

thanks - dave

Yes, that's correct.

>>And then for left-margin-area and right-margin-area, make it as wide as from the paper edge to the margin edge?

Also correct.

>>And what is the measure for inner-margin-area, and outer-margin-area?

This is the same as left-margin-area except that the margin it refers to is dependent on whether the page is odd or even.  See 2.1.1782 Part 4 Section 14.1.2.19, shape (Shape Definition) which contains definitions for these:

inner-margin-area = relative to the inner margin (the right margin for odd-numbered pages, the left
margin for even-numbered pages)
outer-margin-area = relative to the outer margin (the left margin for odd-numbered pages, the right
margin for even-numbered pages)

• thank you. Once you said the odd/even pages it all made sense.
