Text-box width different between IE / FF / Chrome - Causing issues when textbox is filled with 'W's

Question

We have an application that has a text field with a specified length - 4.

Chrome: Firefox:

Is there a way force Firefox / IE to use fixed-width spacing? This is an issue in the case of ID numbers, where the field is actually accepting the full input, but by default not displaying the full width (potentially causing user error if they are typing the field from the screen rather than copy/pasting).

Solution

Instead try changing size attribute to 5. So in all browsers, it will fit.

<input size="5" maxlength="4" value="WWWW" id="txt">
