Guide: How to Make SVG Lines Thicker – Simple Steps Explained

how to make svg lines thicker

SVG (Scalable Vector Graphics) images are widely used in web design, and their popularity is constantly growing. One of the most important aspects of SVG design is the line thickness. In this comprehensive guide, we’ll explore different techniques to increase SVG line thickness and achieve the desired design aesthetics. Whether you’re a seasoned designer or new to SVG, this guide will provide you with the necessary knowledge to create visually stunning designs with thicker SVG lines.

Key Takeaways

  • Creating thicker SVG lines enhances the design aesthetics
  • Understanding SVG line styling attributes is essential
  • Increasing line thickness requires adjusting stroke width, using CSS styling, or utilizing SVG markup techniques
  • Advanced methods such as using vector-editing software and stroke-dasharray can create more stylized lines
  • Following best practices ensures consistent line thickness and optimal design for different viewing devices

Understanding SVG Line Styling

SVG lines can be customized using various styling attributes and properties. Understanding these attributes is crucial for creating visually appealing designs and achieving the desired line thickness.

SVG Line Attributes

The following attributes and properties can be used to style SVG lines:

Attribute/Property Description
stroke Sets the color of the line
stroke-width Sets the thickness of the line
stroke-opacity Sets the opacity of the line
stroke-linecap Sets the style of line endings (values: butt, square, round)
stroke-linejoin Sets the style of line turns (values: miter, round, bevel)

By adjusting these attributes, designers can create various line styles, thicknesses, and colors that fit their design’s context and purpose.

Pro tip: To maintain consistency in SVG line thickness, always use the stroke-width attribute instead of the CSS property border-width.

Next, we will explore different methods for increasing line thickness in SVG.

Increasing Line Thickness in SVG

Once you have a clear understanding of SVG line styling, it’s time to explore the methods for increasing line thickness in SVG. There are several approaches to achieve thicker lines in SVG, including:

  1. Adjusting the stroke width attribute
  2. Using CSS styling
  3. Utilizing SVG markup techniques

Let’s take a closer look at each method:

Adjusting Stroke Width Attribute

The stroke width attribute determines the thickness of the SVG line. By default, the stroke width is set to 1, but it can be increased to achieve thicker lines. To adjust the stroke width attribute, you can use the following code:

<line stroke-width=”3″ />

In this example, the stroke width is set to 3, resulting in a thicker line.

Using CSS Styling

CSS can also be used to adjust the stroke width of SVG lines. This method provides more flexibility as it allows you to apply styling to multiple lines simultaneously. To use CSS styling to increase stroke width, you can use the following code:

<style> line { stroke-width: 5; } </style>

In this example, all SVG lines will have a stroke width of 5.

Utilizing SVG Markup Techniques

There are additional markup techniques that can be used to create thicker lines in SVG. Two of the most popular techniques are the stroke-dasharray and stroke-dashoffset attributes. These attributes can be used to create unique line styles, including dotted and dashed lines. To utilize these attributes, you can use the following code:

<line stroke-dasharray=”10, 5″ stroke-dashoffset=”2″ />

In this example, the stroke-dasharray attribute creates a dashed line by specifying the length of the dashes and gaps between them. The stroke-dashoffset attribute shifts the position of the dashed line relative to its starting point.

By using these techniques, you can achieve thicker and more visually appealing lines in your SVG designs. Experiment with different methods to find the one that best suits your needs.

Techniques for Making SVG Lines Thicker

While adjusting the stroke width is the most common method for increasing SVG line thickness, there are other techniques you can use to make your lines bolder and more visually appealing.

Using Vector-Editing Software

One way to adjust SVG line thickness is by using vector-editing software, such as Adobe Illustrator. This method allows you to manually adjust the stroke width for specific parts of the SVG design. Simply select the line you want to modify, and adjust the stroke width until you achieve the desired thickness.

Using Stroke-Dasharray and Stroke-Dashoffset

Another advanced method for creating bold and stylized lines in SVG is by using stroke-dasharray and stroke-dashoffset attributes. These attributes allow you to create custom patterns and offsets for your lines, resulting in unique and eye-catching designs. Experiment with different values to achieve the desired effect.

Attribute Description
stroke-dasharray Defines the pattern of dashes and gaps used to create the line
stroke-dashoffset Defines the distance between the start of the line and the start of the dash pattern

By utilizing these advanced techniques, you can create unique and visually captivating SVG designs that stand out from the rest.

Best Practices for Thicker SVG Lines

When it comes to making SVG lines thicker, there are several best practices to keep in mind to ensure that your designs look consistent and professional. Here are some tips:

Consider the Overall Design Context

Before adjusting the stroke width of your SVG lines, consider how they fit into the overall design. Ensure that the thickness of the lines is proportional to the other design elements and that it creates visual harmony. Also, ensure that the color and opacity of the lines are consistent with the overall color scheme and design of the SVG.

Select Appropriate Stroke Width Values

Choosing the right stroke width is essential to achieve the desired line thickness in SVG. Ensure that the stroke width values are not too thin or too thick, as this can ruin the aesthetics of the design. Typically, stroke widths between 1 to 4 pixels work well for standard designs, but this can vary depending on the design context.

Optimize SVG Line Attributes for Different Viewing Devices

SVG files can be viewed on a variety of devices, including desktops, mobile phones, and tablets. To ensure that your SVG lines look consistent and visually appealing across all devices, it’s essential to optimize SVG line attributes. This includes the use of vector-based graphics and adjusting stroke width values based on the viewing device’s pixel density.

Use Stroke Width in Combination with Other SVG Line Attributes

Stroke width is just one of the many attributes that can be adjusted to modify the look and feel of SVG lines. For example, adjusting stroke color and stroke opacity can have a significant impact on the visual appeal of the design. Experiment with different combinations of these attributes to create unique and eye-catching designs.

By following these best practices, you can create SVG designs with thicker lines that look visually appealing and professional. Remember to experiment with different approaches and get creative with your designs!


Making SVG lines thicker is a critical aspect of enhancing your design aesthetics. By following the steps outlined in this guide, you can effortlessly increase the line weight in your SVG designs. Understanding fundamental concepts like stroke width, stroke color, and stroke opacity is vital for achieving the desired line thickness in SVGs.

Experiment with Different Techniques

Experimenting with different techniques, such as adjusting stroke width, using CSS styling, or utilizing SVG markup techniques, can help you achieve the desired thickness for your SVG lines.
