Frequently asked questions
Can I resize this stencil?▾
Yes. The PDF is vector so it scales cleanly. Print the pattern at 100% for a 7 to 10 inch pumpkin, 130% for 11 to 13 inch, or 150% for a giant. Use your printer's "Fit to page" or "Custom scale" setting.
What kind of paper works best?▾
Standard 20 lb letter or A4 printer paper is fine. Heavier paper is harder to bend around the pumpkin curve. If your printer supports it, set the quality to 'best' so the lines are crisp.
How long will the carved pumpkin last?▾
Usually 5 to 10 days. Coat all cut surfaces with petroleum jelly and store the pumpkin somewhere cool overnight. Avoid direct sun. Battery LED pumpkin lights produce no heat and help it last longer.
Can I sell pumpkins carved with this stencil?▾
Yes, the carved pumpkin you make is yours. The license covers personal and small-scale commercial carving (selling carved pumpkins, photographing them, posting on social). You may not resell the PDF file itself.
What if my printer doesn't print the whole stencil?▾
Set 'Page scaling' to 'Fit' in the print dialog and uncheck 'Auto-rotate'. If it still cuts off, the design includes 0.25" of safe-area margin so a small crop won't ruin it.

Carving key
White / K: leave skin and flesh intact. Light gray / 1: shallow scrape for a softer glow. Dark gray / 2: deeper scrape for brighter light. Never cut through. These are relative depth levels, not millimeters.
1. Shade the broad silhouette
Shallow-scrape the light-gray body, sail edge and tail surfaces. Leave white separating highlights untouched.
2. Light the sail panels
Deepen the dark-gray vertical sail panels individually. Preserve the pale outer rim and white seams between the panels.
3. Shape the long jaws
Deepen the dark jaw and arm planes carefully. Keep the small white teeth intact; do not cut through any gray area.
4. Finish legs and tail
Deepen the dark feet, belly and tail underside. Use an LED to balance the glow while keeping the entire pumpkin wall continuous.
Previews are simulated. This design has not been physically test-carved. Brightness depends on remaining wall thickness.

AdvancedStegosaurus Pumpkin Stencil
A cartoon stegosaurus with a round friendly face, four chunky legs, and a row of large diamond-shaped back plates fills this hard pumpkin stencil. The body is carved as a wide open pierce, the back plates are pierced individually above it, and the toes and facial details are fine cut-outs. When lit, the dinosaur glows as a bright segmented shape with the plates hovering above the silhouette. Carve the face details and tiny toe lines before removing the large body section, since the body cut-through will flex the pumpkin wall and make those small details harder to control.
AdvancedTriceratops Pumpkin Stencil
A chubby cartoon triceratops in a walking pose fills this hard pumpkin stencil: a large frilled head with three prominent horns, two small oval nostril dots and a crescent eye below the frill, a round body, four chunky legs with pointed toe claws, and a short upturned tail. The frill at the back of the head is an open silhouette that glows as a scalloped arc. Cut the three horn outlines and the two small nostril dots first before the broader body and leg cutouts, as the nostril dots are isolated and easiest to control while the pumpkin is still intact.
