Your Twitter profile picture appears next to every tweet you send. It’s an opportunity to associate an image with your business in the minds of everyone who follows you.

The challenge is that your Twitter profile picture is very small and square. For most businesses, your logo or personal headshot isn’t the right size or shape to represent you well.
If your profile picture is your logo:

Make sure your logo fits into the square size. Cropped-off logos look unprofessional and give the impression that your business doesn’t care about the details.
Make sure your logo is readable. If your logo contains words that cannot be read, you are wasting the space. Create an image without the words that captures the essence of your logo.
Consider switching to a headshot. People connect with faces, not logos. If you are the driving force of your business, why not use your face to make your business seem more human and approachable?
