# Re: [NTG-context] Change of font size affects header text size, too

```

Hello,```
```
in the following example:

----

\starttext
Aaa

\page

\startsection[title={Sec}]
\start
\setupbodyfont[6pt]
\dorecurse{12}{\input knuth}
\stop
\stopsection
\stoptext
----

```
header text size on page #2 is small (6 pt) although body font change was intended only to text inside section "Sec" -
```thus the text "\input knuth" is surrounded by \start ... \stop.

```
How to change the bodyfont size of the running text only (ad-hoc in the middle of the document), without changing header text size?
```
Use \switchtobodyfont[6pt].
