A sundial is an old-fashioned dial used to tell the time. It’s a great project for anyone who loves the outdoors, is interested in history, or enjoys tinkering with home improvement projects. But even if you don’t meet any of these criteria, it’s a fun project that anyone can do with a few materials and minimal carpentry skills.
Building your own sundial is not only educational and insightful but also makes a great addition to your home or garden. Read on to learn how to build a sundial so you can feel like an antiquated genius every time you tell the time!
Why build a sundial?
A sundial is a very simple way of measuring time. It is inspired by the sundials used before clocks were invented. They are not only functional but also beautiful works of art and design objects. They are also a great way to get kids interested in science and design. By building the sundial, they learn about geometry, craftsmanship and the history of timekeeping.
There are even sundials that you can build indoors. There are entire websites dedicated to sundial design so you can build a sundial that suits your style and space. With the right materials and a little patience, you can build a beautiful, functional sundial for your garden or home. It’s the perfect project for people who want to get creative or for kids who want to learn how to build something.
Materials for building a sundial
- A board or plank of wood
- You can use any type of wood for this, but it should be at least 3/4 inch thick. A thicker board makes a sturdier sundial that will last longer.
- marking tools
- Something to mark the wood. Try a pencil, pen, or chisel.
- A square or ruler. This is important to ensure your sundial is straight and level.
- wood stain or paint
- You can paint your sundial any colour you like with wood stain.
- hammer and nails

Step 1: Mark the place for your sundial
Find a spot outside with a good view of the sun. So you can read the time correctly on your sundial. You can also build a sundial indoors by placing it next to a window and tracing the path of the sun’s rays. You can also ask a friend to help you find the sun’s orbit so you don’t feel like it’s an individual project.
Since the sundial will be outside, keep an eye on the weather forecast. Avoid placing the sundial in direct sunlight during the hottest part of the day, as it may overheat it and you. When choosing a location for your sundial, you should look for a place where you can see the sun well.
Step 2: Build the base of your sundial
Before you start building the gnomon (shadow casting staff), build a base for your sundial. The base is what keeps the sundial upright and is what you will later attach the gnomon to. To do this, use a pencil to mark a square or rectangular shape on the wood. Then cut out the shape with a chisel or saw.
Next, sand the edges of the wood so they are smooth and even. Then stain or paint the wood to match the rest of your sundial. Remember that the wood will be on the bottom of the sundial. The stain or paint should not be too thick, otherwise, you will no longer be able to see the course of the sun.
Step 3: Assemble the Gnomon (Shadow Wand)
The gnomon casts the shadow on the sundial that you can use to tell the time. To do this, find a straight stick that is about 2 to 3 inches wide. Avoid branched or knotted sticks as this can break the sundial. You can also use a piece of bamboo or a dowel.
Drive nails into the ends of the stick with a hammer. You don’t need to drive them in very deep, just far enough that the ends of the nails are sticking out of the wood. These will serve as the gnomon’s “legs” once you’ve attached the piece of wood to the base.
Step 4: Mark the hour markers (the stick figures)
After mounting the gnomon on the base and placing the sundial in a sunny spot, you can mark the hour markers on the wood. You can either mark them with a ruler or make a template to carve into the wood. When you score them, use a ruler to measure where you want the 12 marks to go. Then use a chisel or awl to carve a small notch in the wood. Make sure they are flat enough so you can later cut them out with a knife.
Bottom line
A sundial can be decorative or have a real purpose. Imagine you are in the desert and you are lost. In order not to endanger yourself, you must not expose yourself to the midday sun. However, without a watch, this is difficult to determine. A sundial can help with this.
After building a working sundial, you can place it anywhere in the garden or on your patio. It is a great decoration that blends in with the rest of the outdoor decoration. And when your friends and family see them, they will be amazed at your DIY skills.
A sundial is a beautiful addition to any garden or yard. It’s also a great way to get kids interested in science. Building a sundial is an excellent way to learn about geometry, design, and history. If you love outdoor living, this is the perfect project for you.
