View Full Version : Weight plates,Are they accurate?

12-30-2004, 06:51 PM
I've been doing my own research about this,and I found out that weight plates don't weight the same,they are different. For example,in one gym I found standard olympic 45lb plates that weighted only 43.5 on the scale,and I found Ivanko plates that weighted 46 lbs....???
To make a long story short,I found out that plates don't weight the same,a 45 pound plate is usually not a 45 lb. plate,and no scale is the same,they are different too. My qestion is,noticing that plates and scales are different,who is to say what's right and what's wrong?
Is there a standard weight? a standard pound? how can powerlifting meets be done,if the plates are inaccurate? I want answers,I deserve an explanation. :swear:

Dont worry about it , its a few pounds i say... if ur not a big bodybuilder or a pro just forget about it lift hard and let it go

In my gym, the Ivankos are by far the heaviest. It's obvious when you use 1 ivanko and 1 other brand of plate. I always wondered why I couldn't lift the "same" amt of weight w/ ivankos :mad:

milling plates to exact weights is expensive. VERY expensive. So there are usually fairly large tolerances. Deal with it or spend $10 per pound or more for standardised plates.

You got me thinking, Luigi, so I weighed one of my 25 lb plates and my scale said 23 lbs. Either the plate is 2 lbs short or my scale is wrong (it's digital). Either way, I feel cheated. :scratch:

In most powerlifting meets the plates they use are very accurate and cost alot of $. In national meets the plates they use are 'right' meaning they are weighed in to the gram. They cost $23.784.765.00 each though. Well......there expensive;)

Thank you for your replies,your responses helped me a lot,they made me understand many things,they were very helpful. But for us,the average bodybuilder/powerlifter that don't compete ,but like to set personal records,we want to know the truth about how much are we lifting. :windup: :micro:

Sh!t, can't believe I forgot to post about this. The DBs at my gym are heavier than they say! 45s weigh 51lbs, 35s weigh a whopping 42lbs.

heh, when i was just starting awhile back, i was discouraged because i thought i was benching only 100lbs for reps, turns out when i weighed it all, 134lbs :)

That's because they don't include the weight of the handle.

Sure, but some dumbbell sets are right-on.

And people look at me funny when I search the gym for two of the same brand plates. It angers me when I see some1 throw on the "45lb" bumper plate on one side, and a metal 45 on the other, the bumber plates are so chewed up I can't imagine they weigh 40 lbs.

usually i dont care what kind of plates they are, except bumper, there much bigger.

In a way,we all feel cheated because of this. And we have the right to be upset,we pay our hard earned money to go to state of the art gyms,and we think the weight plates are accurate but they are not ,it is so ridiculous,the truth is you never really know exactly how much you are really benching,how pathetic...am I getting too negative? :whip: :evillaugh :micro:

Just lift as much as you can lift. I understand being a little peeved about it, but it's nothing to dwell on.

01-05-2005, 10:38 AM
Yes, you could also think about it like this. how will you ever know how much anything weighs, how do we know scales are acurate?

So a 25 plate weighed 23lbs
so say you're doing a 220lbs lift, assuming the bar is 20lbs.
Thats 4 each side.
Imagine the 4 on the left were 25 and the 4 on the right 25!
Thats 8 lbs more on the poor left arm, very unlikely but def possible.

i lift with weights at home, my heaviest plates are 4 25's and 8 10's then 8 5's and 8 '2.5s. im just getting into it, so it will be a while before i really need more. i weighed all my weights within a day of purchase. 4 of the 10's are 10.5 on my digital scale, 1 of the 25's is 25.5. one of the 5's is 5.5. all the rest of my weights are dead on. to find smaller inaccuracies after i weighed each weight i stacked and put on scale so that a general coming up short or too much would be magnified. none to speak of. my bb weighs 15 lbs, my 2 db handles are 3 each and my things to screw on are .5 lb each. for the first time ever im glad i dont go to a gym. i bought most of my weights at sports authority but have several (2 25's and 4 10's) from some local store. they were where all but one of the innacuracies came from but where easily worth the lower price.

whoever said ivanko weights are off is wrong, because they test their plates and bars to like the gram. they dont mess around w/ their stuff.

Most likely it's the scales that vary and not the plates.

The weights may have been accurate when they were manufactured, but keep in mind, being tossed, shoved, cleaned, racked, dropped, and slammed against other plates, floors, racks, bars, etc. that they eventually chip and disintegrate. we have the same problem in my gym, we just got a new shipment of plates a few months ago. the new plates weight slightly more than what they say, the old ones weigh slightly less. i think they might intentionally make the plates slightly heavier, taking into account the daily beating they recieve.

One time I weighed this 45 plate, but it only weighed 35, but then I realised it actually was a 35, moral of the story is, unless your doing farmers walk why walk a weight to the scale, when you never know what is correct the weight or the scale.
