Welcome to how to draw a sphere!
Hello and welcome fellow artists!
Thank you for visiting this article on my site to learn how to draw a sphere!
I’ll go step-by-step through a few methods for sphere drawing, and most of them focus on drawing spheres not lighting spheres. There’s a distinct difference between drawing forms and adding light and shadow to them.
Drawing solid forms should always come first, then light source, shadows, highlights, etc can come into your picture plane. The goal is to have a solid drawing first, with form space you understand. This makes adding light and shadow so much easier.
I don’t shoot for perfect spheres in all of my examples because there are lots of sphere-like or ovoid forms whose drawing process is nearly identical to spheres. These sphere-like forms are basically variations of a sphere, and it helps to know how to construct those as well.
Let’s dig in! We’ll start by looking at what defines a sphere.
Learning about spheres: The technical stuff and gubbins
Don’t worry, I won’t get too mathematical on you, I promise.
Just as every point on a circle is equidistant from its center, so it is with a sphere. The major difference is a sphere is a three-dimensional form, while a circle is a two-dimensional shape. Shapes, edges, and vertices, and depth create forms, which we also call objects.
So, a sphere is a geometric three-dimensional form whose surface is composed of points that are all equidistant from its center. In general, we use the terms sphere and ball interchangeably, and that’s fine.
Exploration and study: Natural and man-made spheres
We need reference photo materials! We all know what a ball, sphere, sphere-like, and ovoid forms look like, so the value of a reference photo here isn’t really for learning how to draw a sphere. Its value is as a source of inspiration. After learning how to draw a sphere, we’ll want to add surface texture and light–which is where the reference photos come in handy.
Shape breakouts and natural variations
Most objects we see in day-to-day life are spherical or spheroid. That means things like apples, oranges, grapes, water droplets, the human skull, etc are three-dimensional forms that are round, or more or less round. They are not perfect spheres, but they’re visually close enough to be referred to as spheres or spherical.
Here’s a reference board for spherical/spheroid and ovoid objects:
How to draw a sphere step-by-step tutorials
There are three methods I’ll cover here that are strictly drawing only–meaning no tonal value, or light and shade, is used to create the spheres. The first two methods demonstrate how to draw freehand spheres, while the third covers sphere drawing in perspective.
The fourth method I’ll cover here goes step-by-step through how to draw a sphere using light and shadow, both digitally and using graphite. I will demonstrate how to add a light source, form shadow, mid-tone (or half tone), a core shadow, a cast shadow, and a highlight to a flat circle shape to model a sphere. I’ll also demonstrate cast shadow placement using the angle of the light rays from the light source.
In this first method, we’ll draw a sphere by using ellipses to add the illusion of depth to a flat circle shape.
Draw a circle of any size you like, and try to make it as round as you can.
Draw horizontal ellipses within your circle. The band of each ellipse should look and feel like it’s wrapping around the surface of the sphere you’re creating.
This feeling of a contour line wrapping around a form is what ultimately gives our sphere drawing a sense of three-dimensional depth on our picture plane (paper).
Next, repeat the same process from step 2 with vertical ellipses wrapping around the sphere from top to bottom.
The way your ellipses wrap around the edges, or outline, of the circle you started with, is very important.
The illusion of depth is created by giving the viewer the feeling the contour lines are wrapping around the form. This creates a sense of depth because it shows plane changes/turns on the form.
2D forms have no depth, so they have no plane changes to indicate a presence in 3D space. Plane changes are the realm of three dimensions.
Once you’re happy with the sense of depth created by your ellipses, begin darkening the contour lines on the front-facing side of your sphere.
Darkening the contours on the front side, while leaving those in the back lighter, will add a greater sense of depth through value. Darker tones appear to come forward, while lighter tones appear to recede into the background.
To make this process as clear as possible, I created a video to demo the sphere drawing process for this method.
Another method for how to draw a sphere more or less does away with using a circle shape as a starting guide. I don’t find this next method as intuitive or helpful as the method above, but it is another option to consider. It begins with ellipses instead of a circle.
How to draw a sphere: Form dissection
I created the next few videos to demonstrate the form dissection part of how to draw a sphere. When we need to draw something broken, split open, cut up, etc., visual dissection drawing skills come in handy. It’s also useful for investigating and drawing internal shapes and forms, like the juicy insides of a sliced orange or the bloody bits of a battle wound or a sliced-off limb.
The most important thing to remember about the dissection of any form is to do it along believable contour lines, even if you’re not going for a clean look.
Sphere drawing in Perspective
If you’ve visited any of my other how-to-draw articles, first of all, Thank you!
Second, you will have noticed that part of the way I craft these lessons is to demonstrate how to draw the subject in perspective. Perspective drawing is one of the fundamental drawing skills, so I give it a shout-out in each of these articles.
Next, I’ve created a video to demonstrate how some of the process for how to draw a sphere in perspective. As you’ll see in the video, the process is simple but requires quite a bit of repetition.
Below are some images from the video to act as another reference for how to draw a sphere in perspective.
How to draw a sphere with Light and shadow
The first thing to know about how to draw a sphere with light and shadow is that there isn’t a lot of drawing involved, per se.
I consider drawing to be the use of line marks and segments, shapes, forms, etc., which is a bit different than adding value/tones through shading. I think of light and shadow more like painting and coloring, which is why I’m not terribly fond of covering them in how to draw articles. I’m always concerned that it will cause confusion, but it is all connected so we gotta get into it at least a little.
Please try to bear in mind, for how to draw a sphere and anything else you draw, that you always want a solid drawing with solid forms first. Light and shadow, tones and shade, and color and paint all come after you have solid forms.
Okay, I promise I’m done ranting about it. For now ?.
Know your light source
When you’re comfortable with how to draw a sphere, the next step is to add a light source to create light, shade, shadows, and the other values and tones.
First things first, you must know a few things about your light source.
Without diving into the Fundamentals of Light, the four things you must know (or invent and decide on) about your light source are its angle in relation to your object, its height, its color/temperature, and its intensity.
To help you practice, I recommend keeping it simple so there are fewer variables to juggle. I suggest sticking to black and white for now and using a simple light of average intensity. That leaves the height and angle of your light source to play and experiment with.
Here are a few references to help with visualizing your light source.
Form shadow and cast shadows
When lit, all forms will have at least three shadows: a form shadow, a cast shadow, and an occlusion shadow. Of course, in reality, the tones/values are much more involved than that.
Here are a few diagrams to illustrate most, if not all, of the areas and terminology involved in how to draw a sphere with light and shadow.
Lighting your sphere drawing step-by-step (digital)
Now that we’ve very roughly covered a few lighting basics, let’s dive into some demonstration. From experience, I believe the fundamentals of light are more easily practiced with digital tools–they’re much more forgiving. So, this example has been created in Photoshop.
Start with a medium-size flat circle. It helps to use one with some tone rather than a white circle. Here I’ve used a mid-tone gray circle.
In the case of how to draw a sphere with light and shadow, we need to start with a toned flat circle and build the depth with light and shade. Normally, I would not start lighting without a form.
We have a shape to add depth to, now it’s time to decide on the light source.
I chose to emulate the sun here, keeping the source up high, at about a 45-degree angle to the object, far away, and intense.
With the light source set, let’s make the first rough light pass on the object.
The focus here is on determining where your sphere’s terminus/terminator will be by judging where the plane change happens–where the sphere would begin to turn away from the light.
Now it’s time to get into the shade and shading part.
Light helps us see forms, while shade and shadow give us form definition.
In this step, select a dark grey (about 80-85%, or a 2b pencil to 4b pencil if you’re working traditionally) and begin blocking in the form shadow.
The form shadow will begin at the terminus/terminator and cover all parts of the form facing away from the light.
This is also a good time to start blending in your halftone/mid-tone. The halftone/mid-tone area is where the form has started to turn away from the light but hasn’t turned enough to be in shadow. So, this area is roughly half the value of both the center light and form shadow combined.
It helps to remember these are all first passes. It will be necessary to go back over each area to darken, lighten, blend, and adjust as needed.
With your form shadow roughed in, it’s time to add your cast shadow.
The shape and angle of your cast shadow are determined by the shape of your form and the angle of your light source.
It’s okay you’re a little off at first. I’m pretty sure my example here is slightly off, but it works.
A written explanation gets confusing, so I’ll include a diagram for placing cast shadows after this step-by-step tutorial.
Learning how to draw a sphere with light and shadow is a really good exercise for learning about the other important shadows, like the core and occlusion shadows.
You’ll see in the diagrams from steps four and five that I’ve labeled the core shadow. The terminus/terminator is where the light no longer reaches and the form shadow begins. Right next to that is the core shadow, the darkest part of the form shadow.
Occlusion shadow areas are places where the light cannot reach at all–they are occluded, obstructed. Occlusion shadows can be present on or inside of forms as well as part of cast shadows. Wherever the light does not reach, you should have occlusion level darkness of tone/value.
The last step in how to draw a sphere with light and shadow is to add the reflected or “bounce” light.
Reflected light happens when light from the source bounces off other surfaces and is reflected back onto the object–in this case on its form shadow area.
How to determine cast shadow placement
Next, I’ve included a few images to demonstrate how to locate and place the cast shadow for a sphere. Here we’re looking for where the light rays meet the outer contours of the sphere and intersect the ground plane.
How to draw a sphere with light and shadow using pencils (traditional)
Not everyone is interested in working digitally, so I thought it would be helpful to demonstrate how to draw a sphere with light and shadow traditionally as well.
If you’d like to follow along with this demonstration, you’ll need a few pencils. I recommend a blend of the soft and hard leads: 4h, 2h, and h pencils; as well as an hb pencil and a 2b pencil. 4b and 6b pencils will help in the shadow areas. I like to go all the way up to 8b because I love velvety shadows, but usually, 6b is dark enough. I have articles about graphite pencils and drawing tools if you need more information in those areas.
As a rule, I don’t use a blending stump, cotton swab, or cotton ball for this kind of exercise. They smudge more than they blend, so I avoid them.

Here is where those lovely references from the beginning of this article come in handy! While important, sphere drawing on its own isn’t the most exciting exercise. With some imagination and reference, you can create some fun and awesome things from spheres.
