Anyone who uses the internet are conscious about their bandwidth and most of us use a limited data plan, so no one is willing to waste it without extremely strong reasons. Firstly, what is bandwidth? It is the total amount of data transferred through an internet connection. And as we all know, the web pages are the combinations of texts, images, videos, flash, etc. Except the texts, the remaining web elements may consume 100 times more bandwidth. Therefore, it is always a profitable act to optimize the web contents by giving preference to bandwidth. Through this article, I’ve tried to give an estimated idea of how to optimize images for the internet. Here are few basic image sizes which you can use for different kinds of requirements.


150 (width) x 120 (height) or 120 X 150

If you are creating a product catalog or a web gallery or a team profile, you can use this size. It is a reasonable size for creating thumbnail images. It is small in dimension as well as in file size.


320 x 240 or 240 x 320

You can crop your images to this size if you are going to share many photos over an email. If the recipient has slower internet connection, he/she will appreciate your work because the overall image loading time will be decreased due to smaller size of images and yet be clearly recognizable and visible.


640 X 480 or 480 X 640

This image size is preferable while you are going to share an image within an online forum or for emailing purpose. The image size will be big enough to be viewed clearly but with less file size.


800 X 600 or 600 X 800

Preferable while you are going to share some design samples with your clients or an image you are creating for a blog post. The image size is neither big nor small. It will almost fit within the fold without any scrolling.


There is no hard and fast rule to image dimensions that should be used over the internet, but preparing and compressing the images as per its intention will definitely help you save yours and your recipient’s internet bandwidth. Remember, each and every bit of data you transfer over the internet uses electric energy. The more bandwidth you use, the more energy you consume. Save Energy!
