Making custom moon phase posters with the Moon Phase Generator

Difficulty: easy. Time: about 5 minutes. Best methods: printing and framing, plus laser engraving or cutting from the SVG.

The Moon as it appeared on a wedding night, a birthday, or the day someone was born makes an intimate keepsake. This tool computes the exact illuminated fraction and phase for the date, time, and place you choose, and draws the terminator faithfully. Style it as art for a print, or switch to laser mode for a layered SVG ready to engrave or cut.

What You'll Need

Printing: any home printer or a print shop, plus paper or card and a frame
Laser engraving: a wood, acrylic, or slate blank and the layered SVG
Laser cutting: the SVG with the frame layer set to cut
Extras: nothing to install, everything runs in your browser

Step 1 - Set the date and place

Pick a place and choose the month, day, and year, plus an optional time. The Moon's phase and the illuminated side are computed for that exact moment, so the crescent or gibbous shape matches what was really in the sky.

Step 2 - Choose a shape and style

Choose a full, circle, or heart layout, pick a palette or set your own background and moon colours, and toggle the glow and any texture or crater detail.

Step 3 - Add your words

Add the place, date, coordinates, and a personal dedication in your choice of fonts, and add a border frame to finish it.

Step 4 - Export

Download a high-resolution PNG or a print SVG for framing, or a laser SVG with the moon, text, and frame as separate coloured groups. Open it in the Design Editor for further edits.

Home and print-shop printing

Match the size to your paper or frame, or set a custom size in millimetres.
Keep the glow on for a luminous moon, or use a light palette for a minimalist print.
Print the PNG at home, or send the SVG or PNG to a print shop.
Frame it with a matching aspect ratio so the moon sits centred.
