You may recall that I’ve written about Advise in the past, but they’ve changed their name and domain to adJelly.
If you missed my previous write-up about them, adJelly offers a fantastic collection of specs for all the most popular social media sites like Facebook, Twitter, YouTube, Instagram, LinkedIn and more. You simply select the social media site you’re creating ads, images or graphics for in the left column and you’re presented with all the specs you’ll need.
The site is particularly useful for designers because sites like Facebook offer numerous options for sizes. For instance, Facebook offers sizes for single image ads, carousel ads, video ads, video slideshow ads, cover and profile images, post images, event images and more. Plus, specs change frequently, and some sites don’t make it easy to find the specs (I’m looking at you, Facebook!).
