Hi Borrel1804,
Thank you for your question — and please don’t worry, this is a very common and understandable challenge when working with Word documents that have different layouts. You're definitely not alone, and I’m happy to help!
From what you described, it sounds like you're trying to retain inline formatting (like italics) from the source document, but want the pasted content to conform to the page size and margins of the destination document — without bringing over the layout settings from the original.
- Use "Merge Formatting" or "Keep Text Only"
After pasting (Ctrl + V), click the Paste Options icon that appears:
- Merge Formatting (M):
This keeps inline formatting like italics and bold, but adopts the font, margins, and styles of the destination document.
- Keep Text Only (T):
This removes all formatting, but you can manually reapply italics. This is useful if the source and destination styles conflict.
To set this as the Default Paste Behavior:
- Go to File > Options > Advanced
- Under Cut, copy, and paste, set:
- Pasting between documents → Merge Formatting
- Pasting from other programs → Merge Formatting
- Pasting between documents when style definitions conflict → Use Destination Styles

- Ensure “Show Paste Options button” is checked

- Handling Section Breaks and Page Layout
If the issue still persists after using paste options, it’s possible that the source document contains hidden section breaks that carry over unwanted page size and margin settings.
- **Show hidden characters:**Press Ctrl + Shift + 8 to view paragraph and section break marks.
- Avoid copying section breaks: Select only the text, not the section break markers.
- Copy in sections: Instead of copying everything at once, select and copy individual paragraphs.
- Use Styles (Recommended)
- Instead of manually applying italics (Ctrl + I), apply the built-in "Emphasis" style to the text you want to appear italicized.
- You can find it in the Styles pane or apply it via the Hometab.
- Copy and paste using the "Merge Formatting" option.
The text will retain its style structure but adopt the formatting of the destination document.
