Height vs Strength ?

To answer your question from a lifting point of view, there is no question that a tall athlete has a disadvantage when it comes to relative strength comparisons. Shorter athletes, all other things considered equal, will have an advantage on most lifts. There is also a penalty for heavier athletes. Shorter, lighter athletes will tend to have better ratios than taller and heavier athletes.

The lifts you mention are powerlifting, and even in competitive powerlifting this is factored in. For example, in one Federation to qualify for elite at 114, you need to total 1085, a ratio of 9.52 (1085/114). To total elite in the 308class, you need 2040, a ratio of 6.62. When determining the overall best lifter in meets, heavier lifters are given a handicap (total/bodyweight x coeffecient) based on their weight. While no handicap exists for height, there is no question a shorter 198 has the advantage over a tall 198, all other things being equal.

There are actually “relative strength” calculators which will make adjustments based not only on weight, but age, gender etc. Relative strength is not linear with bodyweight, and peaks at around 132 lbs for men and 110 lbs for women. Additional bodyweight will make it progressively harder and harder to reach your relative strength maximum. This in not to say that 132lbs is the best weight for sprinting, but for powerlifting, it seems to be the ideal weight for maximizing relative strength.
