[IBC] trunk width
From: ss
How does one measure trunk size/width, especially when there is nebari, or a slanted trunk? Usuall you measure the circumference at the point where the curve between nebari and trunk stops, then divide by pye (whateevr that is - been a long time since Iwas at school) to find the diameter.

Colin A lot of us, on the other hand, merely lay a ruler across the tree and eyeball the diameter. As for where, as Colin says, the widest part of the trunk is just above the spread of the roots. In real life, one would measure a trunk at breast height -- usually agreed to be about 4 feet -- hence the terminology, "x-feet dbh" for x feet diameter, breast height. You'd have to choose where that was on a bonsai. It probably would NOT be at the thickest point, and since we like to brag about how fat our trunks are (as opposed to ourselves ;-) it would not be the preferred spot.

Ed,
You coudn't teach me how to spell, also, could you?

Thanks and regards ss SS _I_ measure the width, which is called the caliper, at the thickest part ABOVE the nebari. I realize that for many many bonsai this somewhat ambiguous. If I need to be really accurate, I state the distance above some fixed reference at which the measurement is taken, such as the rim of the pot or the soil line, or some artifact on the trunk. This measurement gives the most meaningful 'size'. In general, I am looking for the diameter at the point at which it will stay nearly the same for some distance. That puts it above the buttress. On ebay you are likely to see most anything, including circumference, which almost totally meaningless, or the width of the nebari which might be interesting, but of little value in judging the trunk.

For what it's worth, you can also use tree calipers. I got mine a long time
ago from A.M. Leonard. They're aluminum and spread to about 8-10 inches which will work for most of our bonsai. As mentioned by Colin, you can also measure the circumference and divide by pi.

No need for calculations or eyeballing the trunk. Just find the place Colin talks about, make sure it's level, and adjust accordingly and hold it to a ruler.
