How many times have you clicked out of a website because that large picture wrapping up the entire homepage was loading miserably slow or wasn’t loading at all?
Patience is one thing and money is another. And both were being duped mercilessly in that painful buffering session. While you were at wit’s end with the delay, your Internet connection was equally being strained with a huge bandwidth consumption, not to mention, the dyspathy you were feeling for your otherwise promising data plan.
Bandwidth consumption? But I haven’t downloaded anything as of yet!
Speaking of bandwidth, by definition, it is the amount of online data transferred per second over an Internet connection. And, ‘data’ technically includes texts, pictures, audios, videos and practically all content available over the Internet.
Of all these, the least bandwidth hungry is, but, text content. As such, letters and words do not need long to load, be it any screen size. Of course, audio and video files may take minutes to even hours. But, this is justified and fair enough. What isn’t acceptable here is the wastage of bandwidth for the sake of big, bulky pictures. And yes, you are actually downloading them in the process. So, why not re-size these pictures and make browsing experience a little more comfortable?
Now, what’s this image resizing thing?
Simply put, it’s about reducing the size of a picture to a dimension best suited for a certain purpose, so that it can fit into a website and load anywhere in any browser without a hitch. But, how would this possibly help?
Well, a digital picture is actually an arrangement of a mammoth number of dots called ‘pixels’. More the number of these pixels, the bigger is the size of the picture. And bigger the size, longer shall it take to load. What often is approached wrong is the way we upload full-sized pictures on a website directly from our devices. The second mistake we do is to reduce the size of these pictures in the editor of the website itself. So, when it loads for an end user, the original full-sized picture comes first with the browser, then, attempting to make it smaller. This is where your precious time gets consumed.
But, of course, it should not be much of an issue if only one picture is included in the website. But, if there are many, your bandwidth should be better be dead.
What are the optimum image resizing dimensions?
Keeping it basic, here are the different favorable sizes for different purposes:
150 X 120 and vice versa: This dimension works great for websites that are more of a product catalog sort of. They are essentially the apt size of thumbnail images and hence, go great with team profiles. 150 X 120 is a small dimension and hence every small in size. Such pictures are the most easily loadable ones for any website.
320 X 240 and vice versa: When I’ve mentioned bandwidth, count in emails too. And to share a bundle of picture via an email, 320 X 240 and vice versa is the most apt dimension. This is always a cool option if the recipient has a slow Internet connection or limited data plan.
680 X 480 and vice versa: This dimension proves to be the best option when picture sharing is the matter. The pictures are clear and crisp and the details of it can be viewed with utmost clarity. Moreover, the size of such pictures are small, making them easily and quickly loadable.
800 X 600 and vice versa: This dimension is often preferred for corporate use to share pictures or samples with clients. Such pictures are not too big, neither too small, but easily fit into any screen without making the web page a long scrolling one. Also, 800 X 600 is the perfect picture size for a blog post picture content.
And this is just about image resizing. There’s more to optimizing pictures for the web. Aspects like adding an Alt-Text or a Caption further optimizes the pictures and helps in reducing page load times, making Search Engine Optimization (SEO) a lot easier.
And why SEO alone? Greed for bandwidth also hints toward greed for electric energy consumption. The more the sloth, the more is the wastage of energy. Ditch it and go green and the Earth will be a lot better place to live in.
