Work out smoothie ratio instantly with clear inputs, formula shown and shareable results.
Total volume adds the three components, and the thickness index is the solid fraction: fruit plus dairy over the total, where about 0.6 to 0.7 gives a spoonable texture. Smoothie texture is set by the solids fraction rather than the ingredient list, which is why adding 50 ml of juice thins a blend far more than swapping the fruit.
