It’s not always the most eye-pleasing from an aesthetics perspective, but this is another one that can often yield some pretty dramatic results. Make your main call to action or “submit” button (read my post on why you should stop using the word “submit” on your form submission buttons) big enough so that it’s one of the first things your visitors will notice. Larger buttons are also much easier to click and will help you avoid a bad user experience and frustrating your users. Stop settling for the default browser-generated form buttons. Create something custom that will work nicely with your site or even use just a solid, clickable color block. I’ve made a habit of starting with my buttons around 250 pixels wide by 50 pixels tall.
