1. Build Conservatively and Design With a Purpose
Let's face it: No one likes spending a long time filling out a form. Keep it short and simple and eliminate elements that aren't absolutely necessary or that don't offer a tangible benefit. Make sure every part of your form is pulling its weight, and your users will thank you.
The structure of your form should serve just as much of a functional purpose as its elements. When laying out your form, keep in mind that, at least in the Western world, people read from top to bottom and left to right. They also often use the Tab key to move around the form. Your design should reflect this through intuitive labeling and natural placement of elements. And, of course, your form should never look scattered or haphazard — make sure everything is evenly spaced and neatly arranged.
Here are a few standard form layouts that you should use as a starting point for more creative designs:
Left-Aligned Labels With Vertically Stacked Fields
This form features left-aligned labels with neatly ordered fields stacked on top of one another. This gives the eye an easy-to-follow path down the form, which is especially helpful if you're asking questions users may not be familiar with. Because they're able to read down the list of questions without the visual interruption of an input field, they'll be able to concentrate more on what you're asking. This layout does tend to make for longer form completion times because of the amount of time it takes for the eye to move from the label to the input field.
