How to Create BMI Chart Images at imgresizr.com

Open imgresizr.com and set your canvas to 1200×800px for a landscape chart format. Use the Caption tool to create a BMI reference table with height in the left column and weight ranges for each BMI category across the top. Use colour coding: green for healthy weight, yellow for overweight, red for obese, and blue for underweight — these are internationally recognised health traffic light colours. Add a clear title ("BMI Reference Chart — Adults") and include a disclaimer that BMI is a screening tool, not a diagnostic measure. Include the NHS or CDC as the source. Export as PNG for sharpest table text. Compress to under 500KB for blog or educational material embedding.

BMI Chart Content Notes

  • BMI is calculated as weight (kg) divided by height (m) squared
  • BMI thresholds are different for South Asian, Black, and East Asian populations — note this in educational materials
  • BMI is not suitable for children, pregnant women, or athletes — include appropriate disclaimers
  • Always cite a reputable health source (NHS, CDC) on any health information chart
