Most Black Friday windows fail for the same reason: too much is happening. Five offers, three fonts and a handwritten note taped to the glass all compete, and someone walking past at normal pace takes in none of it. The posters that work say one thing clearly, from a distance, in a second or two.
Lead with one offer
Pick the single message you most want passers-by to read. Usually that is the headline discount: "30% off everything" or "Up to 50% off". Put that on the main window poster and nothing else of equal weight. Secondary offers belong on smaller signs inside or by the till.
If you cannot decide which offer matters most, that is worth settling before any printing. A clear offer printed once beats four offers printed loudly.
Short headline, big number
Keep the headline to two or three words. "Black Friday Sale" is enough. The discount figure should be the largest element on the poster, often larger than the headline itself, because the number is what stops people.
High contrast does most of the work. Black and white with one accent colour, often red, reads well through glass and in low winter light. Avoid pale text on busy photographs; it disappears from the pavement.
One hero poster, a few supporting signs
A simple plan that suits most small shops: one large hero poster in the window, then one or two smaller signs that repeat the message closer to the action. The hero is usually A2 or A1 on a full-height window, or A3 on a smaller frontage. Supporting signs at A4 work on doors, and A5 suits the till or counter.
Our Poster Size Guide has exact dimensions if you are measuring a frame or a gap in the window.
Ideas by type of business
Retail: one A2 or A1 window poster with the headline discount, plus an A4 on the door so the offer is visible as people come in.
Barbers: an A3 in the window with a single offer, such as a set price for a cut, and an A5 at the mirror station or reception for add-ons.
Salons: a clean A3 by reception or in the window. Keep treatment lists for a separate price list poster rather than crowding the sale message.
Cafés: an A4 or A3 on the counter or menu board area, with the offer stated simply. Customers already queuing will read a little more detail, so the counter is where secondary wording can go.
Boutiques: sale signage that matches the shop's look matters more here. A restrained black and white poster with a single figure often sits better than bright red everywhere.
Personalised or ready-made?
A ready-made design is quickest when the standard wording fits. A personalised Black Friday poster lets you add your own business name or sale message. If your design already exists in Canva, Adobe or from a designer, you can upload it and print it as a poster.
