Custom Paint by Numbers: Photo Selection Tips

Requirements for Portraits (People)

How to choose a photo that works well for a custom paint by numbers kit.

Painting a portrait of a loved one, a partner, or a child is a beautiful and highly emotional project! Because human faces are incredibly detailed and we are very sensitive to facial features, choosing the right photo is absolute key to a successful painting.

To ensure your portrait looks realistic and recognizable, please follow these strict requirements for human subjects:

1. 📸 Close-Ups Are Essential (Chest-Up is Best!)

  • The Rule: The face(s) should take up at least 60-70% of the photo. A "selfie-style" or chest-up shot is absolutely perfect.
  • Why? If you upload a "full-body" photo of someone standing far away (e.g., standing in front of a mountain), their face on the canvas will be smaller than a coin. The software will not be able to generate eyes, a nose, or a smile. It will simply become a blank, flesh-colored blob.

2. 💡 Soft, Even Lighting on the Face

  • Please ensure the person’s face is evenly lit by natural light.
  • Avoid photos where half the face is bright and the other half is in a dark shadow. Heavy shadows on a face will be converted into dark brown, grey, or even green paint blocks, which does not look natural on a canvas.

3. 🏞️ Keep the Background Simple

  • A standard kit has a limited number of paint colors. If your photo has a very complicated background (like a busy room, lots of trees, or a crowd of strangers), the software will waste too many colors trying to paint the background, leaving fewer colors for the face!
  • Pro-Tip: Choose a photo with a simple, solid-colored background, or zoom in so the background is mostly cropped out.

4. 🎨 The 48-Color Upgrade (Highly Recommended for Faces)
Human skin tones require very subtle, smooth color gradients. If you use a standard 24-color kit for a close-up portrait, the shadows and highlights on the skin might look like harsh, patchy blocks.

  • We strongly advise upgrading to the 48-Color Option for any human portrait. It provides double the amount of transition colors, ensuring the skin looks soft, natural, and highly realistic.

What if I only have a full-body photo?
If your favorite photo is a full-body shot, don't worry! You have two options:

  1. Crop the photo on your phone to zoom in on the faces before uploading.
  2. keep the full shot and size up so the faces are big enough to paint, using the same sizing as our other guides — 1 person: 12×16″ (30×40cm); 2–3 people: 16×20″ (40×50cm); 4–6 people: 20×24″ (50×60cm); 7+ people: 24×36″ (60×90cm). For any portrait we recommend the 48-Color Option."
