While total muscle creatine stores scale with lean body mass (correlating loosely with weight), the daily loss rate is not highly variable across typical adult body weights (e.g., ~2 grams for a 70 kg (154 lbs) person). A fixed maintenance dose covers this for people ranging from ~50–100 kg (110–220 lbs) without needing precise adjustments, as the difference in required intake would only be ~0.5–1 gram. Loading phases do use weight based dosing (0.3 g/kg/day) to quickly saturate larger muscle pools, but maintenance reverts to a flat amount for simplicity and efficacy. Height is irrelevant, as it doesn't directly influence muscle mass or creatine needs weight serves as a better proxy if any adjustment is considered. Studies show 3–5 grams daily maintains saturation and performance benefits equivalently across body sizes in healthy adults, with no added gains from weight proportional dosing post loading.

If using total body weight Some guidelines scale maintenance slightly higher for larger individuals. For example

A conservative estimate 0.03 g/kg/day = ~3.8 g/day.

A more generous 1 0.04 g/kg/day = ~5.1 g/day.

For athletes over 200 lbs Up to 8 g/day.

If using lean body mass (better for obesity) Estimate your LBM first (via DEXA scan, calipers, or online calculators, for a 127 kg (279.4 lbs) male at 180 cm tall with 30% body fat, LBM might be ~89 kg (195.8 lbs)). Then apply 0.03–0.075 g/kg LBM/day, yielding ~2.7–6.7 g/day. Studies often use LBM based dosing to optimize without over supplementation.

Loading phase (optional) If speeding up saturation, use 0.3 g/kg of body weight (or LBM) for 5–7 days ~38 g/day total (split into 4 doses). But skip if concerned about GI upset.
