I have few questions about WHO charts indicated below.

1. Why are Weight-for-length and weight-for-height charts separate?
2. Why does weight-for-length chart range start from 45 cm to 110 cm and weight-for-height range from 65 cm to 120 cm?

We are now running BSFP in the refugees camp in Bangladesh where the age of the children become a critical issue. We want to use height cut-off point.

The  2 tables provide different height cut-off points. Would you suggest me which one I will use and related documents for justification ( if available).

One table shows age 6-23 months with the range 65-86cm, then 24-59 months as 87-120cm

The other shows 6-23 months 61-86cm, then 24-59 months as 87-110cm

Appreciate if I could get answers.

Weight for length (WLZ) is intended for children under 2, who cannot stand, so the word "Length" is used in this case. There is a difference between length and height. If you take measurements for the same child, lying down (length) and standing (height), you would find a difference in measurements, cause the relaxed body of the child during length measurement will probably be higher the standing one.
This is why you have two tables for length/height and you should use that according to the age (<2) or by using 87 cm wooden stick if you don't know the age. Some older children above two refuse to stand or they may have medical conditions prevent them from standing, so you take their length and add 0.7 cm to when you check the weight for height (WHZ )table.

The chart that starts with 45 cm is basically for <6 months infants if you have a TFC centre and you include <6 months you will need it. Otherwise, use the 6-23 mo and 24-59 mo charts for boys and girls. Please refer to your country's protocol as there are some minor variations in measurement protocols across countries.

The charts can be downloaded from the WHO website:

I hope that helps,
