TREB (MLS) has a 100kb file size restriction per image (although that has been relaxed) before compression, as it speeds up the whole system and transfer to Realtor.ca. So if you want your images to look good aim for that file size. We get pro’s that send us TREB images that are over 1000kb’s which takes us longer to keyboard crunch down to size. It is just a waste of drive space for everyone on all sides, including longer downloads and uploads on both ends.

The bigger issue with file sizes though is that some Pro’s will send us images for print that are 1500x1000px and barely 600kb’s in size, which for smaller inset images is fine, but we also have larger full cover uses for the images and featured images that require higher quality files. As my banker says Bigger is better, as it provides us with higher quality finished results. Since those low resolution files are being compressed heavily from the original out of camera resolution, compression artifacts end up rearing their nasty head and banding can be seen in highlights (skies) and shadow areas even in properly exposed images. Also flat area tints often have damaged shades of colours when being over-compressed. The other extreme is we have been sent high res images in 8304x 4671px size which is overkill, unless designing for a billboard.

A good size for high resolution print at 300dpi is 3300x2550px (most in the 3000-4000px range is good for HD print resolution and helps to reduce jpeg artifacts on a properly exposed image), at that size the majority of printing needs are covered.
