Frequently asked questions

A PDF poster lands in your inbox within minutes. A framed poster takes a bit longer, because it is printed and framed just for you: usually 2 to 5 business days to make, then roughly 3 to 10 days to travel within Europe (5 to 20 elsewhere). We'll email you when it ships, with a tracking link when there is one.

A clear, well-lit photo with a distinct outline works best: a face in profile, a pet in full pose, a favourite person pulling a face. We trace it into a line portrait before matching it to stars, so the clearer the outline, the better the result.

The PDF is a print-ready file by email: a sharp A4 page (looks best at A4 or smaller) plus a page about your constellation. The framed poster is printed on matte paper, set in a wooden frame with a clear front, and sent to your door in A4 or A3, in black, white or natural wood.

Every poster has a QR code that opens our free app. Point your phone at the night sky, follow the arrows, and the app guides you to your constellation, with a few facts about each star along the way.

Yes. One order can hold several posters, one per family member, one per pet, one for the neighbour who feeds the cat. Use "Add another constellation" on the order form.

PDF posters ship for free, being made of pixels. For framed posters we ask our print partner for the real delivery price to your country when you enter your address, and show it before you pay. Delivery is free when your posters add up to $100 / €100 or more.

By default we use the sky where the poster will hang: for a framed poster, the hemisphere of the country it is delivered to; for a PDF, the hemisphere you are in. You can pick northern or southern yourself under "Settings" on each poster in the order form.

We use it for your poster and nothing else. To turn it into a line drawing it is processed by an AI image service (Google Gemini), and the files are stored in the EU. We never use your photo or poster in public without asking you first, and you can ask us to delete everything at any time by writing to contact@constellations.page.

We guarantee a unique constellation: nobody else will ever get the same set of stars as you. Every star in it is real and visible to the naked eye on a clear, dark night (magnitude 5.5 or brighter).

We use real astronomical star data. Your outline is matched to a patch of sky and drawn flat with a gnomonic (tangent-plane) projection, the standard way star charts squeeze a small part of the sky onto paper, so straight lines in the sky stay straight on the poster.
