Highlight the specific paragraphs or table rows where you want the line spacing to adjust naturally before applying any formatting changes.
Disable 'Snap to Grid' in Paragraph Settings
This is the primary method to allow line spacing to respond naturally to varying font sizes, resolving conflicts caused by East Asian document grid settings.
When East Asian language support is enabled, Word often defaults to snapping text to a predefined document grid. This enforces a uniform line height across the document, regardless of whether you increase or decrease the font size. Disabling this specific setting restores dynamic line spacing.
Highlight the paragraph or entire document (using Ctrl + A) where the line spacing needs adjustment.
Right-click the selected text and choose 'Paragraph' from the context menu, or click the small launcher arrow in the bottom-right corner of the Paragraph group on the Home tab.
In the 'Indents and Spacing' tab, locate the checkbox labeled 'Snap to grid when document grid is defined' and uncheck it.
Click 'OK' to save the settings. Your line spacing will now automatically adjust to accommodate the font sizes used in those paragraphs.
Clear Specified Height in Table Properties
Use this method if the text with restricted line spacing is located inside a table row with a fixed height.

Frequently Asked Questions
Why doesn't my line spacing change when I increase the font size?
This usually happens because the paragraph is restricted by a document grid or the line spacing is set to an 'Exactly' value. Unchecking 'Snap to grid when document grid is defined' in the Paragraph settings usually resolves the issue.
What does 'Snap to grid when document grid is defined' mean?
It is a layout feature frequently used in East Asian language typesetting to align characters to a uniform, invisible document grid. This setting forces all lines of text to maintain the same spacing distance, ignoring the actual font sizes used in the paragraph.
Can I set line spacing to automatically adjust for the entire document?
Yes. Press Ctrl+A to select all the text in your document, right-click to open the Paragraph settings, and uncheck the snap-to-grid option. This applies the natural, font-based line spacing document-wide.
How do I fix line spacing issues inside a Word table?
If text inside a table won't adjust to the font size, the row height might be locked. Right-click the table, select Table Properties, go to the Row tab, and clear the 'Specify height' checkbox.
