How to draw a snowflake – A Complete Guide

Why SVG Is Perfect for Snowflakes

Creating snowflakes in SVG is a great way to add a winter theme to your website while maintaining perfect image quality at any size. In this detailed guide, we will cover how to draw beautiful snowflake vector images using just a few lines of code.

SVG is the perfect tool for creating geometric, scalable designs. And what could be more geometric than a snowflake? Snowflakes, with their six-fold symmetry and clean lines, are perfect for showcasing the power of SVG:

• Scalable – Snowflakes maintain crispness at any size, from tiny icons to large backgrounds. They are ideal for icons, logos, and animations.
• Small file size – SVG code is typically smaller than raster images.
• SEO benefits – Search engines can read and index SVG content.
• CSS styles – Easily change the color, size, and stroke width. Snowflakes are easy to animate and dynamically change styles.

Basic Snowflake Structure

Snowflakes possess six-sided symmetry, a manifestation of which is their hexagonal shape. They have six identical branches radiating from a central point at 60-degree intervals. Let’s start with a simple six-pointed snowflake. The basic approach involves:

• Creating one branch.
• Rotating the original branch around the center 60 degrees 5 times to create six branches.
• Adding decorative elements.

Creating snowflakes in SVG requires an understanding of basic concepts, including paths, transformations and reusable elements. In this guide, we will break down snowflake construction and explore the key techniques behind it. To help you understand the use of various SVG elements and attributes, we recommend you refer to the following articles:

• SVG Coordinate Systems and Units – You find the description of the workspace of SVG that is defined by the values of the viewport and viewBox attributes.
• SVG Shapes – You can learn how to create different simple shapes and apply some style properties to them.
• SVG Path Data – This article shows how the paths can be used to drawing various outlines or shapes by combining lines, arcs and Bezier curves.
• Basic SVG Transformations – You find out how to apply the transform functions for graphic objects rotation, scaling, moving, and skewing through the SVG transform attribute and consider code examples for SVG transformations.
• Fills and Strokes in SVG – You will learn how to set different aspects of fill and stroke, including color, opacity, thickness, use of dashing, etc.

Step 1. Create an SVG Document

Every SVG image begins with the <svg> element – it defines your drawing space, just like a canvas for an artist.

<svg width="300" height="300" viewBox="0 0 300 300" xmlns="http://www.w3.org/2000/svg">
  <!-- Your snowflake code will go here -->
</svg>

Let’s break down the purpose of each attribute:

• width and height define the display size of your SVG image on the page – in this case, 300x300 pixels. These values determine how large your snowflake appears in the browser;
• viewBox="0 0 300 300" defines the coordinate system used within the SVG image. The first two numbers (0 0) represent the upper-left corner of the canvas, and the next two (300 300) represent its width and height in coordinate units. With viewBox, your image can be scaled beautifully without losing clarity;
• xmlns="http://www.w3.org/2000/svg" tells the browser that this is an SVG document and ensures correct rendering.

Tip: Always define a viewBox – this makes your SVG responsive, allowing for scaling and cropping. If you’re wondering how SVG viewBox works, its syntax, and practical SVG scaling and positioning examples, please visit the SVG viewBox article.

Step 2. Start with the Basic Branch

Choose your snowflake’s center. In a 300×300 viewBox, the center is typically (150, 150). Snowflakes are symmetrical, so instead of drawing all six branches by hand, we will create one branch and then rotate it. We use the <path> element to draw lines:

<path id="b1" stroke="#03b6fd" stroke-linecap="round" stroke-width="10" fill="none" d="
  M 50,50 L 150,150
  M 50,80 L 80,80 L 80,50
  M 50,100 L 100,100 L 100,50
  M 80,120 L 120,120 L 120,80
  M 110,140 L 140,140 L 140,110" />

Here is what happens:

• Each M command of the d attribute moves the “pen” to a starting point.
• Each L command draws a straight line to the next coordinate.
• The stroke attribute defines the color as icy blue for the <path> element.
• The stroke-linecap creates smooth, rounded corners.

At this point, you have created one branch of the snowflake – think of it as 1/6 of the final design. Now you can customize the snowflake by setting various style attributes on the <path> element.

The following figure shows snowflake branches with different styles applied to the <path> element.

a) The stroke-linecap="round" attribute, which is responsible for the rounded ends of the lines, is not used.
b) The stroke-linecap="round" attribute is used.
c) The fill color – fill="#03b6fd" is used instead of the transparent fill – fill="none".
d) The stroke-dasharray="2 8" attribute is used to change the branch appearance.

Step 3. Rotate the Branch to Build the Whole Snowflake

Instead of copying the same lines six times, we can reuse the branch using the <use> element. We will use a rotation transform to duplicate the branch six times around the center (150,150). This technique is simple yet powerful:

<g id="snowflake1">
  <use href="#b1" />
  <use href="#b1" transform="rotate(60 150 150)" />
  <use href="#b1" transform="rotate(120 150 150)" />
  <use href="#b1" transform="rotate(180 150 150)" />
  <use href="#b1" transform="rotate(240 150 150)" />
  <use href="#b1" transform="rotate(300 150 150)" />
</g>

The result is six identical branches, perfectly rotated around a central point – just like a real snowflake:

Step 4. Add More Decorations

To decorate the snowflake, add a circle to the center for visual weight:

<circle cx="150" cy="150" r="10" fill="#03b6fd" stroke="white" stroke-width="3"/>

• cx and cy define the center of the circle—in this case, it’s right in the middle of our 300x300 viewBox.
• r is the radius.
• fill and stroke define its colors.

And there you have snowflake – elegant, geometric, and completely vector!

Step 5: Animate the Snowflake

To bring the snowflake to life, you can add a rotation animation directly to the SVG file using the <animateTransform> element. This method defines the animation behavior within the SVG file itself, making it completely self-contained and independent of external CSS. Place the <animateTransform> element directly inside the <g> group containing all the parts of your snowflake. This way, the entire group – all branches and decorations – will rotate around the center point (150, 150).

<g id="snowflake1">
  <!-- Rotation animation -->
  <animateTransform attributeName="transform" type="rotate" from="0 150 150" to="360 150 150" dur="30s" repeatCount="indefinite"/>

  <!-- Snowflake branches -->
  <use href="#b1" />
  <use href="#b1" transform="rotate(60 150 150)" />
  ...
</g>

• type="rotate" — defines the transformation type as rotation.
• from / to — specify the rotation angles and the center point of rotation (x y coordinates).
• dur="15s" — sets the duration of one full rotation.
• repeatCount="indefinite" — ensures the animation runs continuously.

The advantage of this animation approach is that it’s fully embedded within the SVG, making it independent of external styles and scripts, and ensuring consistent behavior across modern browsers, even when the SVG is used as an <img> tag or background image. The effect remains portable and self-contained so the snowflake will rotate anywhere on the display. However, it is less flexible than CSS animation, as each <animateTransform> element can only handle a single transform. More complex effects, such as scaling or fading, require additional elements.

Snowflake vector images are ideal for winter-themed websites, festive designs, and interactive elements – from animated loaders and repeating backgrounds to scalable graphics for digital cards and print materials.

SEO Optimization for SVG Snowflakes

To maximize the SEO impact of using SVG snowflakes on your website:

1. Add title and description tags:

<svg width="300" height="300" viewBox="0 0 300 300" xmlns="http://www.w3.org/2000/svg">
  <title>Decorative winter snowflake</title>
  <desc>Six-Pointed snowflake for winter holiday decor</desc>
  <!-- snowflake code -->
</svg>

1. Use semantic file names: save as winter-snowflake-icon.svg, not image1.svg.
2. Add alt text when embedding: <img src="winter-snowflake-icon.svg" alt="Blue crystalline winter snowflake">.
3. Optimize file size: remove unnecessary decimal places and spaces.

So, let’s write the full code for the SVG snowflake (animated-snowflake.svg). It looks like this:

<svg width="300" height="300" viewBox="0 0 300 300" xmlns="http://www.w3.org/2000/svg">
  <title>Decorative winter snowflake</title>
  <desc>Six-Pointed snowflake for winter holiday decor</desc>

  <!-- Define snowflake branch (hidden, only for reference) -->
  <defs>
	<path id="b1" stroke="#03b6fd" stroke-linecap="round" stroke-width="10" fill="none" d="
	  M 50,50 L 150,150
	  M 50,80 L 80,80 L 80,50
	  M 50,100 L 100,100 L 100,50
	  M 80,120 L 120,120 L 120,80
	  M 110,140 L 140,140 L 140,110" />
  </defs>

  <!-- Rotating snowflake group -->
  <g id="snowflake1">
	<animateTransform attributeName="transform" type="rotate" from="0 150 150" to="360 150 150" dur="30s" repeatCount="indefinite"/>
	<use href="#b1" />
	<use href="#b1" transform="rotate(60 150 150)" />
	<use href="#b1" transform="rotate(120 150 150)" />
	<use href="#b1" transform="rotate(180 150 150)" />
	<use href="#b1" transform="rotate(240 150 150)" />
	<use href="#b1" transform="rotate(300 150 150)" />
	<!-- Center decoration -->
	<circle cx="150" cy="150" r="10" fill="#03b6fd" stroke="white" stroke-width="3" />
  </g>
</svg>

Common Mistakes to Avoid

1. Wrong rotation center. Ensure all rotations use the same center point.
2. Forgetting fill and stroke properties. It’s important to follow color definition rules, otherwise, the stroke may become invisible, and the fill will turn black.
3. Inconsistent scaling. Maintain the proportions of decorative elements.
4. Overcomplexity. Start simple and gradually add detail.

Conclusion

1. When creating snowflakes in an SVG file, keep the code clean and reusable. Define repeating elements (such as branches) with the <defs> and <use> tags to reduce file size and make updating easier.
2. Assign id values ​​(e.g. <path id="b1"> or <g id="snowflake1">) when you need to reference or animate specific parts of the SVG file.
3. Always define a viewBox to ensure your snowflake scales correctly on different screens and resolutions without losing its proportions.
4. Remember: real snowflakes are never identical, so don’t be afraid to experiment with asymmetrical details while maintaining the overall six-sided structure!
5. Optimize performance. Create simple paths and avoid unnecessary points and complex filters. Lightweight SVG images render faster, and animations are smoother.
