1. Introduction
Cutout animation (paper-cut animation) is a stop-motion technique in which you animate frame by frame by moving flat figures (paper, cardstock, fabric or photographs) on a horizontal surface and photographing them from above. In home or educational settings, the key to getting a stable result is to keep the device fixed and to have a consistent workspace. This support turns a cardboard box into a foldable, reusable set that makes capturing with a mobile phone easier.
2. Learning objectives
- Understand frame-by-frame logic applied to cutouts (cutout).
- Build a stable support to keep the mobile phone framing consistent.
- Improve light control using side windows (and the option to add extra lighting).
- Create a reusable set that is easy to transport and store.
3. Materials and tools
3.1. Recommended box
Ideal model: 30 × 30 × 30 cm (cubic box, sturdy cardboard).
Box used in the activity: 30 × 22 × 30 cm (practical with a mobile phone; less suitable for a tablet due to workspace/framing).
Main advantage: it folds, is easy to transport and store, and can be reused in several sessions.
3.2. Tools
- Pencil or fine marker
- Ruler or set square
- Craft knife (and a cutting mat or extra cardboard to protect the table)
To reinforce the box:
- Either strong adhesive tape (gaffer/packing tape)
- Or paper fasteners (optional, for reinforcement)
- White paper or cardstock (for the interior)
3.3. Optional (lighting improvements)
- Small LED lamps or desk lights
- Tracing paper/sheet as a diffuser for the side windows
4. Preparation: identify the sides of the box
Before cutting, decide which side will be the “camera side” (where the hole for the lens will go), which two opposite sides will have the light windows, which side will be the front opening (to handle the cutouts), and which side will remain as the back (it is advisable to keep it joined and reinforced to provide rigidity).
5. Build (step by step)
Step 1 — Mark the side windows
On two opposite sides, draw the outline of the windows leaving a 4 cm margin from the edges so you do not weaken the box.
- Measure 4 cm from each edge and draw guide lines.
- Define a rectangular window inside those guides.
- Repeat on the opposite side (with the 30 × 22 × 30 cm box, it is preferable to use the sides with the lower height).
Step 2 — Cut the windows
Cut with the craft knife following the lines. Make several gentle passes if the cardboard is thick.
- Cut on a base to protect the table
- Remove the inner rectangle and tidy the edges if they are uneven.
Step 3 — Locate the center for the camera hole
On the side chosen for the camera, draw two diagonals from corner to corner to find the center.
Step 4 — Make the hole for the lens (3 × 5 cm)
Draw and cut a rectangle of approximately 3 × 5 cm centered. Check that the mobile phone lens can see inside without obstructions.
Step 5 — Define the front opening and trim the flaps
Trim the front flaps to open access. Keep the back side joined and reinforced (with folded flaps, tape or paper fasteners) to strengthen the structure.
Step 6 — Check and reinforce
- Check that the box remains rigid and that there are no weakened areas.
- Reinforce corners or edges with adhesive tape if necessary.
- Tidy uneven cuts to avoid snagging when handling cutouts.
Step 7 — White interior (better lighting)
- Attach a white sheet to the interior face opposite the camera hole. Optional: paint the entire interior white to increase light reflection.
6. Animation grid (workspace reference)
A grid helps maintain spatial continuity and measure displacements between frames.
Quick option (by hand):
- Place a sheet of paper on the interior base of the set.
- Draw a grid (for example, 1 cm or 2 cm squares) and mark a central cross.
- Use the grid as a reference for scale and the position of characters/props.
7. Benefits, reuse and customization
- Foldable: easy to store and takes up little space.
- Portable: suitable for itinerant workshops.
- Reusable: works for several sessions (you only change backgrounds and materials).
- Side windows: light enters and you can add extra lighting.
- Centered hole: more consistent framing.
8. Quick checklist (before animating)
- Is the mobile phone stable, and can the lens see inside without any edges blocking the view?
- Is there enough side light? (If not, add lamps at the windows.)
- Does the interior have a white or neutral background?
- Is the box rigid, without deforming when you handle cutouts?
- Is the grid (if used) aligned with the framing?
