There is much that can be said about digital image quality and size as many factors affect it (for examples of more detailed discussion see here or here).įor the purposes of our WordPress blog I use a simple rule of thumb: I reduce image width to 450-600 pixels for a portrait and 600-800 pixels for a landscape orientation (making sure to lock the aspect ratio so that the resizing automatically adjusts the height). But in many instances you might want to reduce the file size before sharing – for example, when attaching files to emails or uploading them to the WordPress media gallery. When you are sharing photos through many social media, such as Facebook, the files get automatically reduced in size – which helps. This means that if you want to share them online, they will not only eat through your mobile data and online storage allowances, but take absolutely ages to upload/download. On my phone I usually use maximum picture size of 4032×3024 pixels for the ratio of 4:3, which creates a file of 3.5 to 7.5 MB. Photos taken at high resolution and quality can be several megabytes (MB) in size. If you have small amount of storage space on your phone, you can reduce the file size – but it’s better to work out how to redirect storage of your media files to an external SD card instead. This way your photos will look great on a big screen or in print. Each camera app has settings which control this so take your time to find them. General rule of thumb for digital photography is to shoot at maximum image resolution (or size) and at the highest quality. I have had to have a good rummage around to find the right apps and desktop software for this purpose. I am putting it first even though you should do the resizing last because it is important but many of the in-built mobile photo editors don’t do it. The version you see is slightly scaled down while being displayed within the blog post frame which is only 723 pixels wide. The uploaded photo has the same ratio but reduced size to 800×600 pixels and 180KB. I resized it using ResizeMyPix setting max dimention (in this case width) to 800 pixels. The photo was taken at typical digital camera ratio of 4:3 with maximum size 4032×3024 pixels and 3.55MB.
