1. Copy Paper (20 lb): Fine for Crayons and Pencils
Standard printer paper is perfectly fine for crayons and colored pencils. Both tools sit on top of the paper and do not bleed through. If you are printing for toddlers who scribble with crayons, save money and use plain copy paper.
- Pros: Cheap, prints fast, works with any printer
- Cons: Thin — markers bleed through, pages curl when wet
- Best for: Crayons, pencils, everyday printing, high-volume classrooms
2. Cardstock (65-110 lb): The Marker Standard
Cardstock is the thickness that stops marker bleed-through and holds up to aggressive coloring. It also makes finished pages feel substantial — closer to a real coloring book than a printout.
- 65 lb: Good for markers, still feeds through most home printers
- 80-110 lb: Best for watercolor pencils and repeated erasing
- Note: Very thick cardstock may jam printers that lack a rear feed slot
3. Watercolor Paper: For Wet Media Only
If your child paints the pages with watercolor or acrylic, you need watercolor paper (90 lb+). Its textured surface absorbs water without buckling, and colors stay vivid. Skip it for dry tools — the texture actually makes pencil and crayon coverage uneven.
- Cold press: Textured, holds water well — the common choice
- Hot press: Smooth, better for mixed media with fine detail
- Rule of thumb: Dry tools → copy paper or cardstock. Wet tools → watercolor paper.
4. Paper Brightness and Color: Why It Matters
Beyond weight, two paper specs change how your colors look: brightness and shade. They're easy to ignore, but they explain why the same crayon looks different on two sheets.
- Brightness rating (92-100): Higher brightness makes whites whiter and colors look more vivid. Look for 96+ for the best pop.
- Bright white vs. natural white: Bright white gives the truest, punchiest colors; natural/cream white gives a softer, vintage feel
- Off-white and gray paper: Mutes colors and makes skin tones look muddy — avoid for portraits
- Colored paper: Fun for crafts, but it tints everything you draw on top of it
5. Paper Sizes: US Letter vs A4
Most coloring pages are designed for US Letter (8.5x11 inches), but A4 (210x297 mm) is common outside North America. Knowing the difference prevents printing surprises.
- US Letter: The default for our pages — set your printer to Letter or "Actual Size"
- A4: Slightly taller and narrower; pages print fine but may have a small margin difference
- Printing A4 pages on Letter paper: Select "Fit to Page" or the design may clip at the bottom
- Choosing paper size: Match the page size to the paper in your tray — mismatched sizes cause cropping
6. Paper Storage and Reuse Tips
Good paper handling extends your supplies and keeps printouts looking clean. A few storage habits go a long way, especially in humid climates.
- Store flat: Curled or folded paper causes printer jams and wavy printouts
- Keep it dry: Humidity makes paper curl and ink bleed — store in a sealed box or dry drawer
- Reuse misprints: The blank side of a misprint makes a great free drawing sheet for kids
- Test before a big batch: Feed one sheet through your printer with new paper before printing 50 pages
