Create a photo collage poster online – your guide in 5 steps

1. Create a photo collage poster online – What you need

Before you start to create a photo collage poster online, gather the necessary materials – this saves time and ensures a professional result.

• Choose 5–10 favorite photos in high resolution. For a sharp print result, the images should have a minimum of 300 dpi.
• Determine the format: A3 (29.7 × 42 cm), A2 (42 × 59.4 cm), or a custom size. Make sure the aspect ratio fits your wall.
• Select a background color or a subtle pattern. A light gray or a delicate starry background makes the photos stand out particularly well.

> Tip: If you are planning the poster as a gift for a special occasion, pair it with a matching gift link, for example a Personalized Wedding Gift or a Anniversary Gift.

2. Step-by-step: Upload and arrange images

Here is where the real magic happens: You sit at your computer, listening to the quiet hum of the moon in the background, and design your personal wall art.

• Log in & start the editor
• Visit Lumeries and log in with your account.
• Click on "Create Poster" in the menu – the editor opens in a new tab.

• Drag & drop photos into the grid
• Drag your prepared images directly from the file explorer into the empty grid.
• You can freely move each image or align it using the guidelines.

• Measure spacing precisely
• Activate the Grid Tool (top right in the editor).
• Set the spacing to 1 cm – this ensures a harmonious layout, especially for larger formats like A2.

• Adjust image sizes
• Click on an image, hold down the Shift key, and drag the corners to change the size proportionally.
• For a balanced result, the main subjects should be approximately 10–12 cm wide if you are designing an A3 poster.

• Save
• Press "Save" to secure your progress. You can return and continue working at any time.

3. Refine the design – Colors, texts & effects

Now it gets creative: Customize each image individually and add personal accents.

• Brightness, Contrast & Saturation
• Select a photo, open the "Image Edit" panel, and adjust brightness (+10% to –10%), contrast (+15% to –15%), and saturation (+20% to –20%) until the image looks vibrant.

• Insert date or message
• Click on "Add Text" and type the desired date.
• For a romantic touch, you can include the moon phase of the day by using the Moon Phase Calculator and inserting the appropriate phase (e.g., "Full Moon on July 23, 2024") as a small subtitle.

• Choose frame style
• Under "Frame", various options are available: a delicate star frame, a classic wooden frame, or a modern metal look. Choose the style that best suits your living wall.

• Additional elements
• For extra atmosphere, you can include a small Moon Poster from our range – simply drag & drop it next to your collage. More information is available on the Moon Poster product page.
