Do you mean the actual form? or do you mean during development and wring of
code?
You can change the default font for datasheets (opening tables directly) via
tools->options->datasheet
It should be noted that using tables and datasheets directly is not a good
idea for general applications.
In addition, later versions (finally) allow you to set the size of the text
in the sql window. You can find that in the tools->options->tables/queries
tab.
If you are talking about the forms, then you have to re-size, and re-design
them your self..or purchase one of many re-size routines availing on the
net.
The code font size can be adjusted also., and simply go tools->options while
in the code editor.
