Baseline grids are perfect for creating multiple-page layouts that are consistent, professional and appealing. The baseline grid provides you with a series of equally-spaced horizontal guides that make it easy to perfectly cross-align body copy between frames and columns across your whole document.
The baseline grid is overlaid over your page to help you align text. A baseline grid can be applied to the entire document or individual text frames within it, and will align baselines across linked or completely separate text frames.
The baseline grid's Spacing option overrides the leading value of frame text. Setting the grid spacing to the same size as your body text leading means that your frame text should snap to, and perfectly align with, the baseline grid. The baseline grid is blue by default but can be any color you choose.
You can adjust your Document baseline grid for a baseline grid spanning across a whole page or use a baseline grid that has instead been applied only to an individual text frame or table.
Frame-specific baseline grids are useful for text frames that use a different font sizes (e.g. for caption text, quotes, etc) to the main document's body text, where the frame text will adopt its own independent baseline grid rules and not those of the Document baseline grid.
The following settings can be adjusted from the context toolbar:
