A brief a designer can finish

One line: what the viewer should understand. If you cannot write it, do not assign the design. You will pay for three concepts that guess the strategy.

Add the offer exactly as it should appear, including the price if there is one. Paraphrased offers become wrong offers.

Feed, story, reel cover, carousel length. Link an example of the crop that worked. Designers should not discover the aspect ratio at export time.

Say what must be readable at phone size. Often that means fewer words on the image.

Link the logo and the photos they may use. List what they must not use. A brief without links pushes people into random downloads.

Include the due time for internal review, not only the publish time. The gap is where the work actually happens.

Leave room for one round of questions before pixels. Questions after a full design are expensive. A ten-minute check on the sentence is cheap.

Then let them work. Hovering in the file produces a design by committee and a late post.
