Design a city mapHow it works
From a moment to a poster, in three steps
-
01
Set the scene
Search any place on Earth and pick the date - for star maps, the exact time too. Add a title and your own words; the coordinates print themselves. The poster updates live as you type.
-
02
Choose the format
An instant digital download, or a poster rolled in a long cardboard box. Pick the size for your wall - the same options for star maps and city maps.
-
03
We take it from there
Printing, packing and hand-off to USPS take 1-2 business days. Digital files arrive by email right after checkout.
Star map poster
A portrait of the night sky, drawn from real astronomy
Every star map is computed from astronomical catalogs for the coordinates, date, and minute you choose. Constellations, bright stars, and the Milky Way sit exactly where they stood over that place at that moment.
Pick a design theme, add names and a date, and the caption becomes part of the print - a page from a celestial atlas made for one person.

City map poster
Your city, printed street by street
City maps are drawn from OpenStreetMap data, so any address on the planet works - a childhood street, a honeymoon city, the block where you opened your first shop. Zoom in to one neighborhood or frame the whole city.
Choose a theme from gallery-minimal line work to bold two-tone prints, then add a title and coordinates. The map stays crisp at every poster size.

Poster in a box
Museum-grade matte paper, rolled and shipped in a long cardboard box that keeps it from creasing on the way. Frame it your way, or give it boxed - it unrolls like a reveal.
Occasions
A map for the dates that matter
Weddings & engagements
The sky over the venue at the hour of the vows, or the streets of the city where the question was asked.
Anniversaries
Recreate the first date, the first apartment, the first trip - with the date printed into the caption.
New baby
The stars at the minute they were born, with their name and birth details as the title. A nursery classic.
New home
A housewarming gift that fits every wall: the new address, drawn street by street with its coordinates.
In memory
A quiet way to keep a place and a moment - the sky above a life well lived, or the town someone called home.
Graduations & milestones
The campus map, the city of a first job, the night everything changed. If it has a place and a date, it can be a map.
Answers
Frequently asked questions
What is a custom star map poster?
A custom star map is a print of the night sky calculated for an exact location, date, and time. postaMap uses astronomical data to place the constellations, bright stars, and Milky Way exactly where they stood over your chosen place at your chosen moment, then adds your title, message, and coordinates to the design.
What is a city map poster?
A city map poster is a print of real streets drawn from OpenStreetMap data. Choose any address or city in the world, frame the area you want, pick a visual theme, and add a caption with the place name and coordinates. It works for cities, small towns, islands, and single neighborhoods alike.
Which locations and dates can I choose?
Any location on Earth works for both products. For star maps you also pick the date and time - past or future - and the sky is computed for that exact moment. For city maps you choose the address and how far the map zooms in.
What formats and sizes are available?
Every design comes two ways: an instant digital download from $5.95, or a poster shipped rolled in a cardboard box from $19.95. The size - from 8 x 10 to 18 x 24 inches - is chosen at the second step of the designer.
How accurate is the star map?
The star positions come from real astronomical catalogs and are computed for your exact coordinates and time, the same way planetarium software does it. If you compared the poster to the sky that night, the constellations would match.
How long do printing and delivery take?
Digital files are emailed within minutes of checkout and work anywhere in the world. Printed posters leave production in 1-2 business days and ship by USPS, tracked, within the United States only - free as standard, or Priority Mail for $8.
