Weighing your horse

I always thought this was fairly straightforward...but I have been getting a huge range of numbers with different methods, almost 100 lb. difference in some cases. What is the most accurate method of estimating your horse's weight? I've tried:

weight tape (the tape had him at about 640 lbs. average)
[girth x girth x length]/300+50 (this equation but him at 730 lbs. )
various weight calculators around the web put him at 663, but I don't know the math they are using...

ed: actually, I think those calculators are using this method:
Estimated Body Weight = Heartgirth x Heartgirth x Body Length / 330. (For yearlings divide by 301; for weanlings divide by 280)

I have been around horses for 20+ yrs and have always used the weight tape. The weight tape is NOT dead on just like ever other caculations that are floating around on the web. My point however, is the weight tape is a very good & close estimate in my opinion. The weight tape (if done right) should steer you in the right/general direction. :P Just my 2 cents worth!

On that same note: I'm intersted in what others have to say about the topic as well. Always open to learn more.

Well...I did find this. From A&M, so pretty reliable source. I guess I'll go out and try again tonight. I was by myself the other day, so maybe I was off on the body length: he's not full-sized yet, but it was still a stretch for my arms :P

none fo them will be dead on ... pick one and stick with it and that way you can gauge weight loss or gain... just make sure you do it the same each time and the same way

the only true way to get the weight is to put them on a scale adn weight them

I usually don't even worry much with an adult horse aside from just eyeballing general condition. For him, since he is growing so fast, its more to estimate how much dewormer he should be getting. I'm guessing the 640-663 is more accurate than the 730.
