Moasure makes it simple and efficient to measure pool perimeters, no matter the shape. This guide will walk you through step-by-step instructions for measuring different pool shapes, such as rectangular designs with arc corners and more complex kidney-bean-shaped pools.
Tap on the Closed Shape Measurement type in the app.
Turn on your Moasure device by raising it vertically and rotating it 180° back and forth until the LED flashes blue. Once the LED turns red, place the device at your starting point.
Align the reference point of the device with the edge of the pool to ensure accurate measurements.
Identify a memorable starting point and look for obstacles to navigate around.
Plan how to avoid or account for items like fountains or handrails. Use the appropriate path type to either trace around or bypass these objects.
Here's a recap of how we measured the perimeter of this pool.
Place the device at the pool’s edge and begin with a straight line path.
Start walking at a quick, steady pace towards the next corner.
Pause at roughly half way, splitting the measurements into two fairly equal parts.
Pause at the start of the 'arc' measurement.
Switch to the 'arc' path at curved corners.
Place the device at three points: the start, the middle, and the end of the curve.
The app will automatically calculate the best-fit arc after the third point.
Continue measuring, using 'Straight Line' path to navigate around handrails / obstacles.
Ensure you end at the starting point to close the shape. Tap the red stop icon to see the perimeter and area values.
Tap Edit > Edit Background > Add Image.
Upload an aerial view of the pool project.
Adjust size, rotation, and opacity for alignment. Tap Apply to save.
Here's a recap of how we measured the perimeter of this pool.
Align the device’s reference point with a memorable pool edge location for easy return.
Start with the 'arc' path (navigate around the pool handrails) to capture large curves. Place the device at three points for a best-fit arc.
For irregular curves, use the 'trace line' path to follow the pool’s edge.
Switch to the straight line path to bypass small obstacles like handrails.
Use the trace line path when moving along unobstructed curved edges.
Break up longer segments into smaller parts to maintain accuracy.
Return to the starting point to close the shape, and tap the red stop icon to view the perimeter and area values.
Tap Edit > Edit Background > Add Image.
Reduce opacity to better align the measurement with the image.
Toggle between the background and captured measurement to adjust the image placement and tap Apply.
Technique: With motion-based measuring, you must:
Move quickly
Periodically set down the device.
Rotate the device slowly and steadily, not abruptly.
Pausing: Aim to pause when the timer bar is in the green zone and no longer than within the amber zone.
Use Path Types Strategically: Switch between straight, arc, and trace lines as needed for best results.
Notes By following these techniques and best practices, you’re equipped to measure any pool shape with confidence and accuracy using Moasure. Save your files, add background images, and create detailed, professional measurements with ease.
Before starting measuring a site, we recommend to plan where you will start, pause and finish. A good measuring plan will enable you to stay within the time range limits (6-8 seconds) of Moasure by pausing at the right time and decisively place the device down without panicking. If your shape is closed, you can choose the Closed Shape Measurement Type as you will be starting and ending at the same place. For this guide, let's imagine we're measuring an average pool of 6 by 12 meters. We can plan to stop every 6 meters which will be approximately 6 seconds. That way, we will stop approximately 12 times. Another part of planning is thinking about what Path Type(s) we will be using. If the pool is rectangular, we can use Straight Line. If our pool has curvatures however, we need to use Trace Line so we can capture the curved edges. If our pool's edges are straight at some places and curved at others, we can use a combination of straight and trace lines. We can change the Path Type after each pause point (the point at which we place the device down). Last but not least, we need to consider any objects that might be in our way, so that we can plan ahead on how to avoid them. If we use straight line, we can walk right around an object and the round/curved move we make around the object will not be captured as Moasure will draw a straight line between the pause points. If we use trace line however, we would need to switch to Straight Line or Ignore Line to go around the obstacle as going around an obstacle in trace line will trace / capture exactly how we've moved around it. Ignore Line however will not capture how you walk between the two pause points. This is useful if you want that part to be empty on your measurement drawing. Bear in mind however that ignored paths cannot be labelled. If you're interested in labelling where an object starts and ends, you might want to use Straight Line to capture the length of the object and then label where the object starts and ends. Learn more about Labeling in our Edit Label Guide. We're going to measure the pool illustrated below (see illustration 1), which has straight lines only, so we can measure it entirely using the Straight Line path type. It does have some obstacles however. The obstacles are the fountain on the right side and the two sunbeds at the front. Since the pool's edges are all straight, we can simply use straight lines to move around these objects. We will plan to pause at each point where the side moves into a different direction (see illustration 2).
The mental planning picture of start / finish and pause points and where we need to move around obstacles is captured in the following picture.
Now that we have planned out:
Where / when to start, pause and finish (every 6 meters at points the edges change direction)
What measurement type we will use (closed shape)
Where to move around obstacles (at the fountain and sunbeds)
Which path types to use (straight line and potentially ignore line)
We can go ahead and start measuring. As long as we measure with the right technique, we should get a great measurement. Since this is a closed shape, we will be able to see square meters / square footage and get an Error Percentage that tells us how good our measurement was.
