And with May coming up soon, a lot of artists are getting ready for the Mermay challenge.

So, if you’re just as excited as me to draw mermaids, you’re in the right place.

In this post, we will learn how to draw a mermaid tail.

Mermaid tails can be tricky because they do not follow the anatomy of human legs.

They’re close to fish.

The best way to draw a mermaid’s tail is to study the anatomy of a shark or a dolphin.

I will also teach you how to color it with Procreate.

I know it looks complicated.

But trust me, I will break down each step for you so that you can draw this mermaid tail accurately.

If you notice, the tail fins are transparent and it is possible to color it using any digital software. You just have to manipulate the layers.

I’ll explain further on.

I have used an iPad Pro and an Apple Pencil to draw this cartoon style mermaid tail. But you can use any tool – a pen and paper or Photoshop because the drawing method remains the same.

I will also be teaching you how to color the mermaid tail using Procreate. You can use any digital software or you can even use color pencils, copic markers or glitter pens.

The choice is yours.

Let’s begin, shall we?

How to draw a mermaid tail? Easy Step by Step Tutorial

I’m going to break this down into multiple stages so that we can learn how to draw a mermaid tail step by step.

Let’s focus on the outline first.

How to draw the outline of the mermaid tail

Let’s begin with a nice S shape. We’re drawing the S shape so that it’s easier for us to draw the mermaid tail.

Draw a simple S shape

Take your time and draw the S shape.

It doesn’t have to be perfect because we are just going to use it as a guide to draw the mermaid tail.

Next, let’s draw the torso of the mermaid. I am using the dry ink brush in ProCreate.

Draw the torso of the mermaid

Take your time with this because the tummy of the mermaid can be a little tricky to draw.

All-female bodies go inward toward the belly button and then go outward toward the hips as you draw the torso.

Next, let’s add the navel of the mermaid.

Next, let’s draw the transition of the mermaid from the body to the tail.

draw the end of the stomach and the beginning of the mermaid tail

Now, comes the fun bit.

Draw the fins around the mermaid’s stomach.

Let’s start with 1 fin first. It’s a small curve that comes from the back of the mermaid to the center.

Try to align the end of the fin to the S shape we drew earlier.

Draw the fins of the mermaid

And now, let’s draw the other fin.

Draw the other fin of the mermaid tail

They’re like small C shapes that curve around the belly of the mermaid.

They’re two individual fins so we have to draw them separately.

Think of it like petals or ears.

Next, comes the major portion of the tail.

We’re going to use one long sweeping motion to draw the huge S shape curve. Don’t worry if you don’t get it right the first time, you can always erase it till you feel it looks good to you!

Draw a long curvy line for the mermaid tail

Remember, the tail is broader near the hips and slowly narrows down as we reach the end. So, while you’re drawing your curve, slowly move the curve towards the S shape we drew earlier.

This guide will really help you draw the mermaid’s tail.

Once you’re done, let’s draw the other side of the tail.

In the same sweeping motion, draw the other side. Remember to make the mermaid tail narrower as you go down south.

Complete the mermaid tail

Now, we are done with the major portion of the tail.

I’m going to erase all these rough lines so that we can see the tail clearly.

Erase all the rough lines of the tail

Oh, that looks much better!

Okay, let’s draw the fins at the end – otherwise known as a the tail fins.

This is slightly tricky because the fins of the mermaid are extremely expressive and flowy. So, it’s okay to take your time with this.

Let’s draw 1 tail fin at a time.

Draw the tail fin of the mermaid tail

Think of drawing petals on a flower.

This makes drawing the tail fins of the mermaid much easier! Okay, now, let’s draw the other.

I’m going to overlap the second fin over the first just to make the mermaid tail look more organic.

Draw the second tail fin of the mermaid tail

Remember to attach the tail fins to the tail! Otherwise, your mermaid tail is going to look very odd.

And would you look at that, we’ve finished drawing the outline of the mermaid tail.

Let’s move on to coloring it!

How to color the mermaid tail in Procreate – step by step

Okay, we have the outline ready.

Let’s begin with the torso of the mermaid. I’m just going to go with nice peachy skin tone.

Color the torso of the mermaid

I’m going to add a slight shadow to the torso. So, I’m just going to go with a color a little darker than the skin tone and color the side of the torso with it.

Add a shadow to the torso of the mermaid

Next, I’m going to color the tail a nice green. It’s between green and blue.

You can go for any color. Let your imagination run wild!

Color the tail of the mermaid

Notice that I colored the part of the tail underneath the fins (near the torso), that’s because the fins are going to be transparent.

So, remember to color the tail till the torso!

Next, let’s color the tail fin. I’m going to go for a brighter green.

Color the tail fin of the mermaid a lighter green

Now, whether you’re on Photoshop or Procreate, it doesn’t matter.

Simply change the opacity of the layer to 40%. By decreasing the opacity, we make the layer transparent.

Decrease the opacity of the layer

Now, I’m going to do the same thing to the next tail fin of the mermaid.

Color the second fin on a separate layer of the mermaid tail

Remember to color the other tail fin in a separate layer over the previous layer.

I’m going to adjust the opacity now to 40% and I’ll get this result!

Decrease the opacity of the layer

If you’re enjoying this tutorial and would like to learn how to draw hands and legs, you can think of purchasing this book. It really helped me understand anatomy.

Now, I’m going to add some texture to the tail fins.

I’m going to use a light bluish green shade to draw the lines on the fins.

This layer has to be separate and it should be on top of the previous layers.

Only the outline layer will be on the most top.

Now draw the lines on the tail fins

Once we draw the lines on one fin, repeat it for the next tail fin.

Draw the lines on the second tail fin

And now, we’ll repeat this whole process for the fins near the tail.

So, I’m going to color the fins first:

Color the fins around the mermaid's stomach

I’m using the same green I used for the fins.

Now, I’ll adjust the opacity to 40% so that the fins become transparent and we can see the mermaid tail underneath the fins.

Decrease the opacity of the layer

And now, with the same bluish green shade, I will draw some lines on the fins to give it more depth.

Draw the lines on the mermaid's fin near the torso

Okay, we’ve finished drawing the base colors of the mermaid tail.

Now, you can stop here or you can do a little more to add more definition to the mermaid tail.

I’m going to show you how I draw the scales on the mermaid tail.

How to draw the scales on the mermaid tail

Every mermaid tail you see on the internet will be drawn differently.

Some artists prefer to draw the scales very realistically and make them look like fish scales.

However, if you are drawing a mermaid in a cartoon style, it is best if you keep things simple.

I like drawing everything in a simple cartoon style.

So, what I’m going to do is enunciate some scales on the mermaid’s tail to add some texture to the tail.

First, let’s add a shadow to the mermaid tail to give the drawing more depth.

I’m going to use a medium purple tone on a separate layer over all the other layers (except the outline layer).

Draw the shadow of the mermaid's tail

Once I’m done with the outline of the shadow, I’ll go ahead and color it in.

Color the shadow of the mermaid's tail

It looks weird but I’m going to change the blending mode of this shadow layer to “Multiply” and then decrease the opacity to 40%.

Simply click on the “N” of the layer in Procreate to change the blending mode and decrease the opacity.

Change the layer setting to multiply and decrease the opacity in Procreate

Now, we’ll draw the scales.

Let’s start with a light greenish blue shade and I’m going to color some spots on the side like this:

Add scales to the mermaid tail in a light greenish blue tone

And now, with a darker green, I will add some more spots. Feel free to let some of the spots touch or overlap. It looks more realistic.

Add scales of another color to the mermaid tail

And finally, I’ll add some bright green spots to the tail to make the tail pop with color!

And now, I’m going to add some highlights to the illustration to complete the look!

Let’s pretend the light is coming from the left side. So, I’m going to add a new layer and use a bright blue to draw the highlight.

Add a blue highlight

Now, adjust the blending mode of this layer to “Add” and change the opacity to 17%.

This is the best way to add light to your drawings.

Decrease the opacity and change the layer settings to add.

And voila!

Conclusion + Resources

I hope this in-depth tutorial was super helpful to you, and you were able to learn how to draw a mermaid tail from scratch.

Mermaids are definitely a whole new area of drawing because they don’t follow basic human anatomy.

Learning human anatomy itself takes so much time. So, don’t panic if you can’t get the tail right immediately.

You can also take a look at different mermaid poses and illustrations on Google and Pinterest.

Use that as inspiration to keep practicing mermaid tails.
