If you want to make a paper cube that’s big, sturdy, and actually works first time, this method is about as simple as it gets.
In this tutorial, you’ll learn how to make a cube out of paper using one sheet of A4 — carefully designed with 7 cm squares so you get the largest possible 3D cube from a single sheet. Instead of guessing or using random folds, this approach uses a clean grid to create a perfect cube paper template that folds into a solid shape.
It’s not traditional origami, but it uses the same ideas — precise folds, clean creases, and turning a flat square sheet of paper into a structured origami cube. If you’re into easy origami, paper crafts, or just want to learn how to make something practical, this is a great place to start.
I also walk through this step by step in my video, so if you prefer to follow along visually, you can watch the full cube tutorial there.
What You Need
- One sheet of A4 (copy paper works perfectly)
- A ruler
- A pencil
- Pair of scissors
- Glue
You don’t need special origami paper here — just regular paper on a flat surface.
Step 1: Make a Square Grid
To make a proper cube paper template, we’re going to divide the sheet into equal squares.
- Place your paper on a flat surface.
- Measure and mark at 7 cm, 14 cm, and 21 cm across the width.
- Do the same down the length: 7, 14, 21, and 28 cm.
- Join the marks to create a grid.
You’ll end up with rows and columns of square pieces of paper (7 cm each). This is the foundation of your 3D box shape.
Quick note: A4 is supposed to be 21 cm wide, but it’s often slightly off. Trim the excess so all your squares are even — it makes assembling the cube much easier.
Step 2: Lay Out the Cube Net
Now we shape the cube.
- You’ll use 4 rows of squares.
- The middle section becomes the main body (this forms the sides of the cube).
- Add tabs on:
- Row 1 (left and right)
- Row 3 (left and right)
- Row 4 (left, right, and one end)
These tabs are what let you fold and glue everything into a solid origami cube (even though this is more structured than traditional easy origami).
To create tabs:
- Draw diagonal lines from corners (toward the center).
- Make each tab about 1.5 cm wide.
- Use the corners (right corner, left corner) as guides.
Step 3: Cut the Shape
Now cut out your template.
- Cut along the outer edges.
- Don’t cut into the main squares — those are your cube faces.
- Remove any extra paper outside the grid.
You should now have something that looks like a cross-shaped cube paper layout with angled tabs.
Step 4: Fold Everything Cleanly
This is where your cube starts to take shape.
- Fold along every line.
- Fold the paper in half along the grid lines to create clean creases.
- Use a ruler or pencil to press down and crease the fold neatly.
Focus on:
- Folding upward along each line
- Keeping edges straight (top and bottom aligned)
- Making sharp creases, this is what gives you a clean shape of a cube
Step 5: Assemble the Cube
Now bring it together.
- Start from the bottom (the section without a top flap).
- Fold the sides upward.
- Apply glue to the tabs.
- Press each tab against the inside faces.
Tips:
- Use the table to keep edges straight.
- Fold the right corner and left corner tabs inward neatly.
- Make sure each edge meets cleanly — that’s what makes it look like a proper 3D cube.
At the top:
- You can glue it closed
- Or leave it open like an origami box
If you’ve done it right, you’ll end up with a sturdy paper cube made from a single sheet.

- How to fold and assemble cleanly
It’s much easier to follow visually, especially if you’re new to paper and fold techniques or different origami styles.
What You Can Do With Your Cube
After learning how to make a cube out of paper, don’t stop at one!
This isn’t just a craft, it’s actually useful.
- Turn it into dice
- Write spelling words on each side
- Make a gratitude cube (also on my YouTube channel)
- Use it for games or learning activities
Once you know how to make a cube out of paper, you can scale it, decorate it, or experiment with other origami cube designs.
