Visualise vertical rhythm instantly — overlay a custom baseline grid on live text to perfect your typography.
Baseline grids are the foundation of consistent vertical rhythm in digital design. They ensure that text lines, images, and UI elements align to a common vertical pattern — creating a calmer, more professional look.
When every line of text falls exactly on the grid, readers experience a subconscious sense of order. This tool helps you preview that alignment instantly, directly in the browser.
Without a baseline grid, spacing between paragraphs, headings, and images often feels arbitrary. Consistent rhythm improves readability and makes your design feel more polished — especially on content-heavy pages.
Adjust the baseline step, then tweak your line-height so that it becomes a multiple of that step. Notice how the text naturally locks into the grid.
