# [NTG-context] How to calculate the height of text of a certain width?

```Hello dear All,

the following MWE works best:```
```

\definelayer[LAY]
\starttext

\setlayerframed[LAY]
[x=0pt,y=20pt]
[frame=on,
width=300pt,
align={right,}]   % tolerant}]
{\input ward }

\flushlayer[LAY]
\stoptext

Now, it could have a favourable effect on designing a page if the height of a
text
of certain width could be calculated in advance, depending of the font.
Is there a way?

As I fear, TeX's means "\setbox" woun't work with aligned texts.

Best wishes, remain healthy,
Rudolf
