Square Post Text Layout Simulator
Preview how your text wraps, sizes, and aligns on a 1:1 square slide before you design it
See exactly where your lines break before you build the slide. This tool renders your headline and body copy on a 1:1 square mockup — the format used for carousel posts and card news slides — so you can tune the wrapping, font size, and alignment for maximum readability while you're still writing.

How to use
- Write the headline (Title) and the body copy (Paragraph) that will go on the slide.
- Use the sliders to change the font size, line spacing, and text alignment.
- Check that the line breaks fall naturally on the 1:1 mockup, then copy the finished text structure.
FAQ
- Any tips for line breaks that make a slide easier to read?
- Break your lines at natural phrase boundaries — where a thought pauses — using a manual line break (Shift+Enter) instead of letting the text wrap wherever it lands. The live preview here lets you test each break point and see which one reads best.
- Will the line breaks I see here match exactly what apps like Miricanvas or Canva produce?
- Not necessarily — font choice and letter-spacing settings vary slightly between tools, so the exact break points may shift a bit. Treat this simulator as a way to figure out where you'd naturally want a line break by meaning, then fine-tune once more inside your final design tool.
