Attribute for <INPUT ...>
SIZE =integer

SIZE sets how wide a text or password field should be. It has no effect on any other type of field.

<FORM ACTION="../cgi-bin/html/mycgi.pl">
age: <INPUT TYPE=TEXT NAME="age" SIZE=2><BR>
first name: <INPUT TYPE=TEXT NAME="first" SIZE=10><BR>
last name: <INPUT TYPE=TEXT NAME="last" SIZE=30><BR>
cosmic plane of origin:<BR> <INPUT TYPE=TEXT NAME="plane" SIZE=70>
<P><INPUT TYPE=SUBMIT VALUE="submit">
</FORM>

gives us these fields of various length:

SIZE does not set the maximum length of what can be typed in. Use MAXLENGTH for that. Avoid setting SIZE to a length of 1. Although 1 is technically a valid size, many browsers have a hard time rendering a field that short. Try a size of 2.
