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.
