In this blog post we have shared the All Size TMT Bars Length and Weight Chart [Complete List with Easy Formula]. Here we have answered some popular and important questions related to standard length and weight of TMT bars. The weight of every size TMT bars are also expressed here.

8mm, 10mm, 12mm, 16mm, 20mm and 25mm size/dia TMT bars length chart and TMT bar weight chart (on per piece, per meter, per bundle basis) are covered here.

When a person buys a steel bar from a retailer, on many occasions, one hears complaints that the bar taken from the retailer is underweight. Another the most important thing is that if a steel bar has weight less than or more than standard weight, that steel bar is not of good quality. So before buying TMT steel bars, you must know about the standard length and weight of each size TMT bars.
