If this operation should not be undone, load this document in TRichView via stream, change font in all styles:
for i := 0 to RVStyle1.TextStyles.Count-1 do
RVStyle1.TextStyles.Size := NEWSIZE;
and save it back.

You may use
Increase:
RVStyle1.TextStyles.Size := RVStyle1.TextStyles.Size + 1;
Decrease:
RVStyle1.TextStyles.Size := RVStyle1.TextStyles.Size - 1;

yes, i am doing it this way. but this data is loaded via dbrichviewedit from blob stream, dataset is set to edit mode, than i have made changes and finally i post the changes. than it looks like richview rollback changes 
and font size doesnt change.

Possible ways:
1) Loading in non-db TRichView, changing fonts and saving it back
(See Demos\Delphi\DB Demo\2 RichViewEdit\)
2) Loading in DBRichViewEdit (not DBRichView, it cannot save data), making changes, calling DBRichViewEdit.Change to inform the table that changes have been made, calling table.Post (See the "Example 1" in the help topic about TDBRichViewEdit)
