City map poster generator: make a free map poster of your city

If you are looking for a city map poster generator — a way to make a free map poster of your city — the short answer is that you don't need a picture generator, you need the map as a vector file. Pick the area, pick a style, download SVG or PDF, then add the frame, the type and the caption in any graphics editor. Step by step below — and honestly: we hand you the vector file, printing stays on your side.

Why vector, not a screenshot

Posters are printed large — A2, A1, 50×70 cm. A screenshot falls apart into pixels at that size: the resolution is fixed, and enlarging it adds no detail. Vector stores street lines, building outlines and water fills as curves, so the edges stay clean on a business card or on a banner. And vector is editable: roads sit apart from buildings, water apart from greenery, so you recolour the whole thing into your own palette in a couple of clicks.

Step 1. Choose the area and the proportions

Decide up front what the poster shows: the historic centre, the whole city, or the neighbourhood you live in. Rule of thumb — the smaller the area, the more recognisable streets fit into the frame.

Match the shape of your selection to the print size right away. A-series sheets (A4, A3, A2, A1) have a side ratio of roughly 1:1.41, the popular 50×70 cm is 1:1.4, US 18×24 inches is 1:1.33. Select a square area and print a portrait A2, and you get empty bands top and bottom — a fine look, but it should be a decision, not a surprise.

Step 2. Pick a style

The style sets the character of the poster. Thin minimal lines on white are the classic interior-map look. A dark background with light streets reads graphically. Drafting blue gives the feel of an architectural plan. Treat the style as a starting point: the exact palette is easier to tune in your editor, where you see the whole layout together with the type. A breakdown of the available styles is in Map style customization.

Step 3. Download SVG or PDF

For design work take SVG — it opens in Illustrator, Inkscape, Figma and Affinity Designer with the layers intact. PDF is handier when the file goes straight to a print shop. PNG only makes sense as a social-media preview: it is raster and will not survive large-format printing. One detail of the builder: pick the "PDF vector" tile — the tile labelled simply "PDF" gives a raster PDF (sheet up to A2, 300 dpi), fine for viewing and sign-off but not for a poster on a plotter. The format comparison is in Which format to choose for print and design.

Step 4. Build the poster in your editor

The map is the base. What turns it into a poster is the layout around it:

1. Place the map on an artboard of the right size and leave margins — usually 5-8 % of the sheet width on each side, a little more at the bottom.
2. Set the city name large, with the country or district smaller underneath, letter-spaced.
3. Add a coordinates line: 55.7558° N / 37.6173° E. It is the signature device of these posters, and it is what makes the map personal.
4. Thin things out: switch off layers with small labels and minor roads if they turn into noise.
5. Tune the stroke weights. Arterials slightly thicker, service lanes thinner — that creates hierarchy and lets the drawing breathe.
6. Mark the spot if the poster is about a place: a thin circle or a small heart where the flat is, or where the proposal happened.

What to send to the printer

Print shops normally ask for PDF: convert colours to CMYK, convert fonts to outlines, add a 3 mm bleed if the map runs to the trim edge. At a copy shop, check the maximum sheet — A3 is available almost everywhere, A2 and larger usually needs a plotter.

We do not print anything. We hand you a clean vector file; where you take it — a local copy shop, an online print service, or the plotter down the hall — is up to you.

Easier — get a ready file straight away

There is no need to assemble the data by hand: select an area on osm2cdr.ru, choose a style and download the map as SVG or PDF. It is free and takes under a minute. The data is OpenStreetMap; credit OpenStreetMap when you publish.

In short

• A "poster generator" is really an area, a style, and a vector file at the end of it.
• Take SVG for your editor and PDF for the print shop; PNG is preview only.
• Match the shape of the selection to the print size before you export.
• The city name, the coordinates line and a marked spot turn a map into a poster.
• The file is free; printing is on your side.
