Recaptcha fixed image size

Question

Why is recaptcha image fixed in size 300x57 ? Even when customizing the div where the image is injected, the width and height of the div are overridden and set to 300x57. Of course the image can be re-sized after it's rendered, but why there are no options to generate the image the size developers would like it to be.

reCAPTCHA will rely on the presence of HTML elements with the following IDs to display the CAPTCHA to the user: An empty div with ID recaptcha_image. This is where the actual image will be placed. The div will be 300x57 pixels

Thank you
