English elm weighs about 560 kg m and dutch elm about 580 kg m when dried.
Wood is categorized into two groups based on their density as softwood and hardwood.
Growth rings and grains are often irregular.

The wood of the hard elms sometimes referred to as rock elm generally range from 41 to 47 lbs ft 3 while soft elms typically have a density from 35 to 38 lbs ft 3.
The density of a wood is determined based on the multiple growths and physiological factors such as age diameter height radial growth geographical location site and growing conditions etc.
Notably the english elm and wych elm both have single intermittent rows of smaller earlywood pores.
When wych elm is heavily burled few can argue its supremacy as one of the most sensational of all timbers.
Drying although releasing its moisture fairly rapidly there is a very marked tendency for the wood to distort and there is some liability for collapse to occur in thick sizes.
