How do I measure for steel landscape edging?
When it comes to creating a well - defined and aesthetically pleasing landscape, steel landscape edging is an excellent choice. As a supplier of Steel Landscape Edging, I understand the importance of accurate measurements in ensuring a successful installation. In this blog post, I'll guide you through the process of measuring for steel landscape edging, from understanding the basic concepts to dealing with more complex scenarios.
Understanding the Basics
Before you start measuring, it's crucial to have a clear idea of what you want to achieve with your landscape edging. Steel landscape edging can be used to separate different areas of your garden, such as flower beds from lawns, or to create a border around a patio or walkway. The type of project you're undertaking will influence the measurements you need to take.
First, you'll need to identify the perimeter of the area you want to edge. This is the distance around the outside of the space. For simple geometric shapes like rectangles or circles, there are straightforward formulas to calculate the perimeter.


- Rectangles and Squares: If you're edging a rectangular or square area, the perimeter (P) is calculated using the formula (P = 2(l + w)), where (l) is the length and (w) is the width. For example, if your flower bed is 5 feet long and 3 feet wide, the perimeter is (2(5 + 3)=16) feet.
- Circles: For circular areas, the perimeter, also known as the circumference (C), is calculated using the formula (C = 2\pi r), where (r) is the radius of the circle. If your circular garden has a radius of 4 feet, the circumference is approximately (2\times3.14\times4 = 25.12) feet.
Measuring Tools
To measure accurately, you'll need the right tools. Here are some essential tools for measuring for steel landscape edging:
- Tape Measure: A good quality tape measure is a must - have. Look for one that is at least 25 feet long to handle larger projects. Make sure it's flexible enough to follow curved edges.
- Stakes and String: Stakes and string can be used to mark the outline of the area you want to edge. This is especially useful for irregularly shaped areas. Drive the stakes into the ground at key points around the perimeter and then tie the string between the stakes to create a visual guide.
- Marker or Chalk: You can use a marker or chalk to mark the measurements on the ground or on the string. This helps you keep track of the distances as you measure.
Measuring Irregular Shapes
Not all landscape areas are perfect rectangles or circles. In fact, many garden beds and landscape features have irregular shapes. Measuring for these areas requires a different approach.
- Break the Area into Smaller Shapes: One way to measure an irregular shape is to break it down into smaller, more manageable geometric shapes. For example, if your garden bed is a combination of a rectangle and a semi - circle, measure the rectangle and the semi - circle separately and then add the perimeters together.
- Use the String Method: As mentioned earlier, stakes and string can be used to mark the outline of an irregular area. Once you have the string in place, measure the length of the string using a tape measure. This will give you the approximate perimeter of the area.
Accounting for Overlaps and Joints
When installing steel landscape edging, you'll need to account for overlaps and joints. Overlapping the edging pieces helps to create a seamless and sturdy border. The amount of overlap required depends on the type of edging you're using.
Typically, you'll need to overlap the edging pieces by at least 2 - 3 inches. This means that when you calculate the total length of edging needed, you'll need to add a little extra to account for the overlaps. For example, if your measured perimeter is 20 feet and you're using edging pieces that require a 2 - inch overlap, you'll need to add a few extra inches to the total length to ensure proper installation.
Measuring for Curved Edges
Curved edges add a soft and natural look to your landscape. However, measuring for curved steel landscape edging can be a bit more challenging.
- Flexible Measuring Tape: Use a flexible measuring tape that can easily follow the curve of the edge. Start at one end of the curve and slowly work your way around, keeping the tape measure as close to the ground as possible.
- Multiple Straight Measurements: If the curve is not too extreme, you can take multiple straight measurements along the curve and then add them together. This method gives you a rough estimate of the length of the curve.
Considering the Depth of the Edging
In addition to measuring the perimeter, you also need to consider the depth of the edging. The depth of the edging determines how well it will hold back soil and grass.
- Standard Depth: Most steel landscape edging is available in depths ranging from 4 to 8 inches. For a typical flower bed or garden border, a depth of 6 inches is usually sufficient. However, if you're dealing with a high - traffic area or a slope, you may want to choose a deeper edging.
- Measure the Depth: To measure the depth, use a tape measure to measure from the ground level to the desired depth. Mark this measurement on the edging before installation.
Measuring for Metal Raised Garden Bed Edging
If you're using steel landscape edging for a raised garden bed, there are a few additional considerations.
- Height and Length: In addition to measuring the perimeter of the raised bed, you'll need to measure the height of the edging. The height of the edging will depend on the depth of the soil you want to hold in the raised bed. Most raised garden beds are between 6 and 12 inches deep.
- Corner Angles: Raised garden beds often have corners. Make sure to measure the angles of the corners accurately. Some steel edging comes with pre - bent corners, while others may require you to bend the edging on - site.
Double - Checking Your Measurements
Once you've taken all the measurements, it's important to double - check them. A small measurement error can lead to problems during installation.
- Measure Twice: Go over all your measurements at least twice to ensure accuracy. Compare your initial measurements with the second set to make sure they match.
- Verify with a Second Person: If possible, have a second person help you verify the measurements. Two sets of eyes are better than one, and they may catch any errors or discrepancies that you missed.
