Gap Calculator — Simple Spacing & Layout Tool for Site Work

Gap Calculator instantly works out the exact spacing you need between bars, balusters, pipes, tiles, or panels — so you get clean, even gaps every time, without struggling through fractions and manual math on site.

MULTI-LANGUAGE SUPPORT

Available in Hindi (हिंदी), Bengali (বাংলা), Marathi (मराठी), Gujarati (ગુજરાતી), Odia (ଓଡ଼ିଆ), Telugu (తెలుగు), and Tamil (தமிழ்) — so you can work in the language you're most comfortable with.

Type the way you actually talk on site — use familiar local terms like "सूत" (Soot), "সুতা" (Suta), "દોરો" (Doro), or "நூல்" (Nool) instead of confusing fractions. Just enter "3 inch 4 soot" and get your answer instantly.

HOW IT WORKS

1. Enter your Total Span (the inside measurement of your frame or area)
2. Enter your Material Width (the width of your bars, pipes, or panels)
3. Choose how you want to calculate:
• Optimize Gap – tell it your minimum and maximum acceptable gap, and it finds the perfect spacing
• Fixed Quantity – tell it how many pieces you're using, and it tells you the exact gap
4. Get an instant, accurate result — rounded to a real, measurable size (1/16" or 0.5mm) so it's actually usable with your tape measure, not just a theoretical number
