Step-by-Step Guide on Creating a Paper Cone


Cones are great geometric shapes that have many uses in various activities and lessons. Whether you are interested in 3D geometry or need a cone for a craft project, making one out of paper is a simple and fun way to do it. In this tutorial, we will show you how to make a cone with paper using three different methods.

To start, you will need a piece of paper, a ruler, and a pencil. The size of the paper and the cone you want to make will determine the dimensions you need. For a starting point, a piece of paper measuring 8.5 x 11 inches or A4 size is usually a good choice.

Method 1: The Circular Method

To use the circular method, begin by drawing a circle on your paper. You can either trace around a circular object or use a compass to draw a perfect circle. Next, draw a straight line from the center of the circle to the edge. This will be the slant height of your cone.

Now, carefully cut out the circle and then cut along the straight line. You should now have a sector of a circle. Take the cut edges and join them together to form a cone shape. Use glue or tape to secure the edges in place.

Note: This method works best for learners who are interested in the geometric properties of cones and want to explore the relationship between a circular base and a conical surface.

Method 2: The Triangular Method

The triangular method is a simpler way to make a cone and is often used when making paper party hats or other crafts. To begin, start with a rectangular piece of paper. The length and width of the paper will determine the size of your cone.

First, fold the paper in half lengthwise and then cut along the fold to create two equal segments. Take one of the segments and fold it in half again, creating a smaller, narrower triangle.

Next, fold the open edges of the triangle towards the fold, creating a slant height for your cone. Adjust the angle of the fold to make the cone taller or shorter as needed. Once you are satisfied with the size and shape, join the edges of the folded triangle together to form a cone.

Note: This method is easier for younger learners or those who are more interested in the crafting aspect of making cones.

Method 3: The Amphibient Method

The amphibient method is an optional way to make a cone and is best used when precision and accuracy are important. This method involves using a wooden cone template to create a more professional-looking cone.

Start by finding a wooden cone template that matches the size and shape of the cone you want to make. Using this template, trace around it onto your paper and cut out the shape. Carefully fold along the lines of the template, creating creases that will guide you when folding the paper into a cone.

Once the paper is folded along the lines, carefully refold the paper so that the edges meet in the centre. Use glue or tape to secure the edges together, adjusting the shape and size of the cone as needed.

Note: This method requires more materials and may require additional tutoring or help from an experienced cone maker.

So, whether you choose the circular, triangular, or amphibient method, making a cone with paper is an enjoyable and educational activity. By following these steps, you can easily create cones of different sizes and shapes to suit your needs. Have fun making cones and enjoy exploring the many uses of this versatile geometric shape!

How to Make a Cone with Paper

Making a cone out of paper is a simple and fun project that can be done by anyone. Whether you need a cone for a school project or just want to create a craft, this tutorial will guide you through the steps of making a cone with paper.

Step 1: Start by drawing a straight line on your paper. This will be the base of the cone. Make sure the line is long enough to fit the size of cone you want to make.

Step 2: From the starting point of the line, draw two additional lines that converge towards a single point, forming a triangle. This triangle will be the shape of your cone.

Step 3: Cut the triangle out of the paper using scissors. Make sure to carefully follow the lines you drew to ensure the shape is correct.

Step 4: Fold the triangle in half along the base, joining the two edges together. This will create a smaller triangle with a crease down the middle.

Step 5: Refold the triangle along the crease you just made, forming a smaller triangle with a pointed apex. This will be the top of your cone.

Step 6: Apply glue along one of the edges of the smaller triangle. Carefully roll the paper into a cone shape, making sure the glued edge is at the bottom.

Step 7: Hold the cone together for a few moments to allow the glue to dry and secure the shape. You can also use a paper clip or tape to hold the cone in place while the glue sets.

Optional: If you want a more polished look, you can trim the excess paper from the top of the cone using scissors. This will create a flat surface at the top.

These five steps outline one method for making a cone with paper. There are other ways to create a cone, such as using a circular piece of paper or the “rolling” technique. Feel free to experiment and find the method that works best for you.

If you need further assistance or want to see a visual demonstration, there are many tutorials available online. YouTube is a great source for cone-making lessons, with various tutors providing step-by-step guidance. Simply search for “How to Make a Cone with Paper” and you’ll find plenty of helpful videos.

How to Make a Cone

If you want to learn how to make a cone, it’s a simple and fun project that you can do with just a few materials. Whether you’re making a cone for an art project or for a treat holder, this step-by-step guide will show you how to create a cone using paper.


  • 1 sheet of paper (preferably lightweight)
  • Scissors
  • Glue (optional)

Step 1: Making a Circle

To start, you’ll need to create a circular shape as the base for your cone. Take your sheet of paper and fold it in half diagonally. This will create a triangle shape. Use a pencil or pen to draw a curved line from one corner of the triangle to the opposite corner. Make sure the line is slightly curved, rather than perfectly circular.

Step 2: Cutting the Circle

Next, cut along the curved line that you drew in the previous step. Be careful not to cut all the way to the edges of the triangle. You’ll end up with a segment of the triangle that resembles a circular shape when unfolded.

Step 3: Folding and Gluing

Now, take the circular segment you just cut and fold it in half diagonally to create a smaller triangle. Then, fold the triangle in half again to form an even smaller triangle. If you’d like, you can use a small amount of glue along the edge to hold the cone in place. However, this step is optional as the folding will keep the cone intact.

Step 4: Joining the Edges

To complete your cone, join the two edges of the folded triangle together. Make sure to overlap the edges slightly and glue them in place if desired. This will give your cone a more secure shape. Trim any excess paper along the bottom of the cone to create a straight edge.

Step 5: Enjoy Your Cone

Once your cone is complete, it’s ready to be used for whatever purpose you had in mind. Whether you’re using it for an art project or as a treat holder, you can decorate and customize your cone as desired. You can also make multiple cones using this method to create a set or enjoy making different sizes and heights.

Three Ways to Make a 3D Cone with Mathematics

If you’re interested in learning how to make a 3D cone with mathematics, there are three great techniques you can try. These methods use mathematical principles to create cones without the need for folding or gluing any paper. Whether you’re a learner, tutor, or just someone interested in geometry, these techniques are a fun way to explore the world of cones.

  1. Circular Sector Method: This method involves using a circular sector and folding it to form a cone. To do this, you’ll need a ruler, pencil, and paper. With the ruler, draw a right triangle on the paper with one side as the hypotenuse and the other side as the short leg. Next, find the centre of the circle and draw a circular sector using the right triangle’s hypotenuse as the radius. Cut out the circular sector, then adjust the angle to form a cone shape and glue the sides together.
  2. Triangular Prism Method: This technique uses a triangular prism to create a cone. Start by drawing a triangular base with the height you’d like for your cone. Cut out the triangular base and roll it into a cone shape, making sure to keep the edges aligned. Glue the edges together to secure the cone shape. This method is great for learners who are more comfortable with triangular shapes.
  3. Sector Segments Method: This method involves using sector segments to construct a cone. Begin by drawing a circle on the paper, then divide it into several equal sector segments. Cut out one of the sector segments and adjust its shape to form a cone. Glue the edges to keep the cone in place. This technique is great for visually understanding how cones can be made from circular shapes.

These three methods provide different approaches to creating cones using mathematics. Whether you prefer the circular sector, triangular prism, or sector segments method, you can easily make a 3D cone without the need for complex folding or gluing. Have fun exploring the world of cones with these mathematical techniques!
