Leading spacing changes when copy and pasting type from 1 ID file to another ID file

[Diva14]

Been having this issue for awhile on a few files, but now it is happening more often. When copying text between 2 different ID files the leading changes. See attached screen shot.

Use paste without formatting.

I’m coping and pasting the entire text box and it’s changing from document to document. I did try pasting without formatting and it still isn’t keeping the leading spacing, or the font weight.

[BobLevine]

Does the file you're copying to have an identically named style?

[Jongware]

Yup.

Is the text in one document aligned to the baseline grid, and not in the other?

If both are aligned to the grid: is the grid at the same distance?

If no to both: if the leading value is "(Auto)" (or a number between parenthesis, which also indicates "Automatic"), is the Autoleading value in Justification different?

[Diva14]

Neither file has baseline grid align on and the leading is not Auto.

I’m coping and pasting the entire text box and it’s changing from document to document.

As Bob suggests, formatting changes usually are caused by copying and pasting text with styles (either Object, Paragraph, or Character) that have the same name, but different definitions in the source and destination. For example the [Basic Paragraph] or [Basic Text Frame] styles with different defintions in the two docs.

[BobLevine]

Or even with a different name could be based on an identically named style with different definitions.

[Diva14]

Paragraph and Character styles are none. Object only seems different in the footnotes option. I noticed when looking at the Paragraph pallet that the space after is what is not copying over from document to document, is the footnote spacing the same thing?

[rob day]

There isn't a none Paragraph style—an existing style could be based on the [No Paragraph Style], but unless you have explicitly selected all of the text and broken the style links there would be some style applied.

You could try breaking the style links. Before you copy and paste select all of the text, and choose Break Link to Style from the Paragraph and Character Styles panel.
