The short version
- A strong poster idea is one concept that can be understood from a distance in a couple of seconds, not a collection of elements.
- Event posters work best when one fact, usually the date or the name, dominates and everything else is small.
- Shop and business posters should carry one message and one action, because people read them while walking past.
- Wall posters for homes and studios can be quieter and more abstract, since they are looked at many times rather than once.
- Common print sizes at 300 dpi are A4 at 2480×3508 pixels, A3 at 3508×4961 pixels and 18×24 inches at 5400×7200 pixels.
On this page
The best poster ideas start from a single concept you could describe in five words: one giant number, a word cropped off the edge, a colour field with tiny type. Choose the concept by where the poster will hang. Event posters need one dominant fact, shop posters need one message and one action, and wall posters can be quieter because they are seen every day. Below are thirty concepts, ten for each, plus the sizes and a two second test to check any of them.
The two second poster test
Before you fall for a concept, make a rough version, shrink it to the size of a stamp on your screen and look away. Look back for two seconds. If you can tell what it is for and the one thing it says, the idea works. If you see a busy rectangle, simplify before you refine. The method behind this is covered in poster design.
Fails at a distance
- Six things all the same size
- Thin type on a busy photo
- The key fact in the corner
- Decoration filling every gap
Reads at a distance
- One element far larger than the rest
- Bold type on a calm area
- The key fact at the optical centre
- Empty space doing the framing
Event poster ideas
Gigs, talks, markets, screenings, fundraisers. Pick the fact your audience cares about most and make it the poster.
- The giant date. The day of the month fills the sheet; everything else sits in a strip below.
- Name as texture. The act or event name repeated in rows until it becomes a pattern, one row in a different colour.
- Cropped headline. A huge word running off two edges. People complete it in their heads, and that holds attention.
- One object. A single photographed object on colour: a vinyl record for a listening night, a whisk for a bake sale.
- Countdown sheet. "3 weeks" printed large, replaced with a new poster each week until the day.
- Ticket stub. The whole poster laid out like an oversized ticket, with a perforation line and seat number.
- Map pin. A simplified street map with one bright pin where the event happens.
- Lineup ladder. Names stacked by importance in three sizes, nothing else. Band poster design has more for gigs.
- Split day and night. Left half light for the daytime programme, right half dark for the evening.
- Question poster. One question set large ("Who made your clothes?") with the talk details small underneath.
Idea 1, the giant date, at A4.
Idea 10, the question poster, at the same size.
Poster ideas for shops and businesses
Window and counter posters are read by people who are walking. One message, one action, and a look that matches the rest of your brand. For glazing and placement, see window signage design.
- The single word. "Open." "New." "Fresh." One word in your brand colour, filling the window.
- Price as hero. The offer or price set large, product named small. Works best when it really is the reason to come in.
- Today's special. A poster template you reprint daily with one line changed, so regulars learn to look.
- Behind the counter. A portrait of the person who makes the product, with their name and one line.
- Before and after. For salons, cleaners and repairers: two halves of one image, divided by a clean line.
- Seasonal colour swap. The same layout reprinted in four seasonal palettes through the year.
- Big arrow. For side streets and upstairs shops: an arrow and "Coffee this way", nothing more.
- Review as headline. A short, real customer comment set like a book quote, with permission and their first name.
- Opening hours as design. Hours set in a strong grid that doubles as decoration.
- QR with a reason. A code with a clear promise next to it: "Scan for the menu", "Scan to book".
Idea 16, the seasonal swap: one layout that stays put while the colours and words change each season.
Wall poster ideas for home and studio
A poster on your own wall is seen hundreds of times, so it can be quieter and reward a second look. Colour, texture and a few words go a long way.
- Colour field. One soft gradient filling the sheet, no words at all. Gradient posters shows how to print them cleanly.
- Your city's coordinates. Latitude and longitude in small type on a large field of colour.
- One line you live by. A favourite sentence in a quiet serif with lots of space around it.
- Swiss grid study. Circles, bars and a few words on a strict grid. See Swiss design for the rules.
- Song lyric typographic. A lyric set in one typeface with one word emphasised.
- Palette poster. Five swatches from a place you love, each labelled with its hex code.
- Year in colour. Twelve bands, one colour per month of a memorable year.
- Big initial. One letter, your own or someone you love, cropped and huge.
- Recipe poster. A family recipe set beautifully for the kitchen wall.
- Triptych. Three posters in one palette and three moods: dawn, noon and dusk.
Colour field posters live or die on smoothness. Large prints of soft gradients can show stepped bands; a little grain hides them. Print gradients covers what printers need from you.

The poster size guide lists more sizes, with bleed and margins. Most event posters also need a social version, and the concept should survive the change: a giant date works at A3 and at 1080×1350 alike.
How to make a poster idea your own
Every idea on this list has been done before, and that is fine: what makes a poster yours is the colour, type and texture you bring to it. In Gradiently, the background can be a Mark, a living gradient that, once you claim it, only you can export with. It keeps the words readable wherever they land and renders at every size from A5 to 18×24 inches. Poster templates are in the Studio to start from.
Questions people ask
What makes a good poster idea?
One concept that reads from a distance in a couple of seconds, such as a giant date, a single object or one bold word, with everything else kept small.
What should an event poster include?
What it is, the date and time, the place and how to get in or get tickets. Make the most important of those the largest element.
What size should I make a poster?
A4 (2480×3508 pixels), A3 (3508×4961 pixels) and 18×24 inches (5400×7200 pixels) are common, all at 300 dpi.
How do I make a poster stand out?
Make one element much larger than everything else, use a colour nobody nearby is using, and leave empty space around the main message.
