The Ultimate Image Guide
Images nowadays account to more than 60% of a website’s total bandwidth so it is crucial to have good quality, striking imagery.
So let’s start with the basics that make up an image. A pixel, ‘Picture elements’. Think of it as a roman mosaic made up of lots of little tiles, step away, and they have created one whole lovely image.
Now we know what makes up an image, let’s move onto DPI or ‘Dots Per Inch’. As a rule of thumb, the higher the DPI, the more information there is in an image, so the more detail you can see, the crisper it looks. Please see an example below on how much the correct DPI can affect your graphics/imagery.
As you can imagine, the higher the quality of an image, the larger the file size so it is important you are saving files in their correct format to ensure you are saving space but still keeping the quality you began with.
If you are sending images across to go on your print, website or social media, your designer will need the correct type of file and quality to ensure it is high quality. Please see small guide below.
For print, 300dpi is usually optimal, but you can get away with less, even 150dpi is often acceptable for photographic images, though it would start to lose quality for things such as logos.
