Why sketch? This is why!


What is the purpose of sketching and why should you draw sketches? You might think that you’d rather spend your time for a real drawing than waste it on a sketch. But sketches have crucial advantages over drawings, because when we sketch we train our eye and improve our skills.

What is a sketch?

A sketch is a simplified, rough representation of a living being, a thing or space. It captures an idea, a moment or a figure on paper.

In most cases, a sketch is a draft or concept of upcoming artwork. A drawing study is a series of sketches drawn on something specific.

In rare cases, such as Leonardo da Vinci, the sketch itself is considered a piece of art.

How to learn to see correctly

When sketching, don’t think that you need to know the source well to make good sketches. Rather, we get to know the sources through sketching, because sketches are small training sessions in which we improve our skills.

Even sketches as complex as those of a human face or body will become easier to do by sketching regularly.

The difference between a sketch and a drawing

While drawing is all about details, textures and shading, a sketch is just a quick snapshot. The goal is to capture shapes and to estimate proportions in the shortest possible time with the least amount of drawing effort.

In short: we must be able to translate a concept of the original correctly onto paper.

Sketches as a basis for paintings or drawings

There is no better basis for a drawing or painting than a sketch. It doesn’t matter whether you draw the sketch on a separate piece of paper and use it as a reference for the new work or draw directly onto the sketch.

A sketch should be viewed like a plan where we have already fixed all mistakes. Thanks to our sketch, we know exactly how wide the distances are, where shadows will lie or what the proportions will look like.

It is always good to build up a sketch before you start drawing or painting, as this will save you time if errors occur later. With watercolour paintings, for example, it is often even wanted that the sketch shines through the watercolour.

Sketches as a source of inspiration

Every sketch should be kept. Individual sheets can be stored safely in a folder or box or you can use a sketchbook directly, which can be stored safely almost anywhere.

Keeping the sketches is so important because old sketches can be a very personal source of inspiration. I personally like to look at sketches from my school days in my oldest sketchbook and develop new ideas from them. Therefore, I strongly recommend that everyone keeps all sketches. The question What should I draw? is usually answered after looking at your old artwork.

Which pencil is best for sketching?

Should you ever find yourself in the situation of making a sketch on wet paper, I recommend a pencil with a hardness grade of 6B or higher.

If you want to make a sketch on dry paper, I recommend HB for studies.

However, if you want to draw a finished drawing on top of your sketch, it is better to use 2H or harder, so that the lines of the sketch are not visible later.

I have no time for sketches!

That sentence is easy to say, but is it true? If we’re honest with ourselves, maybe we just don’t take the time for it.

10 to 15 minutes can already be enough time for a sketch. It doesn’t matter if you sketch your coffee cup in the morning, the view from the window or something from your Instagram feed because with every sketch we learn something new.
