# Thread: Weight to Height ratio?

1. ## Weight to Height ratio?

I have been wondering this for a while and want to know if anyone has an answer to this....

If there are two people who have the same frame (proportional to their height) and are directly proportional to each other in muscle, fat, etc, basically the same in everything except height. If one person is an inch shorter, how much more must the taller person weigh to achieve the same proportion of musculature.

Im just looking for a rough estimate here so I can compare my progress to my friends' who is a few inches taller than me. thanks to anyone who responds.

2. It depends on the heights of the people.

Example:

If one person was 10 inches tall and the other person was 9 inches tall it would be a much bigger differance than if one person was 100 inches tall and the other was 99 inches tall.

lets say 5'10 and 5'11

4. my very fast and rough way is 1'' = ~12pds.so if you're 6' 200, if you were 6'3 i'd guestimate you to be 236ish. *shrug* works more or less

5. My guess is 5lbs.

I've always equated 5'8 160lbs = 5'9 165lbs = 5'10 170lbs etc.

So for example if you were 5'6 145lbs and wanted to determine what you would weight if you were 6'8 it would be 215lbs.

Investigate the body mass index calcualtion

nah nah nah not to see if your overweight, because obviously it doesn't take into account muscle. It's very useful to compare the figure you get to others. Basically it lets you know if you are larger for your height than them.

thanks that helps a lot

10. I remember reading an article by Steve Reves that was similar. For every inch up to 6' add 5lbs. For every inch over 6' add 10 lbs.

Correct.

13. it depends on how tall and how much weight gained. tell us how tall youand your friend are, and how much both of you gained, then we can tell you who has done proportionally better.

Spot on.

Some people think it's 10 pounds per inch, but they couldn't be more wrong. In actuality it's closer to the 5 pounds CerealKiller guessed, at least for people of normal height.

As Rik suggested, you can just use the body mass index to find out this information.

Since the system is most accurate in a person of normal height and weight we'll calculate how much heavier a 5'11'' man should be than a 5'10'' man of identical weight ( relative to height ).

We'll say the 5'10'' man weighs 154.3lbs ( 70.0kg ), giving him a body mass index of 22 ...

( to calculate your body mass index, you need to convert your height and weight to metric - in this case 5'10'' 154lbs = 1.78m and 70kg - multiply your height in metres by itself, and then divide that number into your weight. In this case 70 / 3.1684 = 22 )

Now we calculate a 5'11'' man's weight at the same bmi ( 22 ).

I'll be real exact here to get the most accurate figure, I'll call 5'11'' 1.8054m to make it PRECISELY an inch more than 1.78m ... and working with that, the 5'11'' man would weigh 72.03kg / 158.8lbs to be the the exact same size as the 5'10'' 154.3lb man. A difference of approximately 4.5 pounds ...

BUT - one more thing to take into account. Body mass index becomes more inaccurate the taller you get, it's geared towards someone of average height. It doesn't take into account the fact that people grow out ect as well as up. A bmi of 22 on a 5'10'' guy is not the same as a bmi of 22 on a 6'8'' guy. A bmi of 22 would be average on the 5'10'' guy but skinny on the 6'8'' guy.

The best estimate I can give as to exactly how much increasing or decreasing height from the average ( roughly 5'10'' for a man ) affects your bmi is roughly 1 whole bmi point for every 5.5 inches above or below 5'10'' - i.e 5'10'' @ a bmi of 22 = 6'3 1/2'' @ a bmi of 23 and so on.

Taking that into account I would estimate you would have to add around 1/3 of a pound to how much heavier you should be at an inch taller for every inch above 5'10''.

i.e in men of normal weight the difference between 5'10'' and 5'11'' is about 4.8 - 4.9 pounds ... but the difference between a 6'5'' and a 6'4'' man would be closer to 7 pounds and so on ...

Weight also affects it. Obviously if you're comparing two 250 + pounders the difference per inch is going to be more than comparing people of the same height who are of normal weight. Off the top of my head I think it's something like 0.5 pounds for every 40 or so pounds you are above the norm bmi ( 22.5 ). If you're 100 + lbs above you'd have to add 1.5 pounds or more. It's something like that. You have to factor in height as always too. I can calculate it if anyone REALLY wants to know, but what I guessed is pretty close.

But anyway, the difference between a 5'10'' and 5'11'' man with a bmi of 22 is about 4.85 pounds ... so there you have it. I hope this answered your question adequately, BoSox

Thanks Rik.

Made an error or two I had to go back and edit, though, kinda complicated stuff :|
