How To Measure For A Threshold Ramp
If you’re seeking safe and easy wheelchair access in your home, then a rubber threshold ramp is often the way to go. But before you go clicking add to cart, you need to make sure it's the right fit by accurately assessing the height, length and width required.
It’ll only take a few minutes, whereas failing to measure (or taking improper measurements) could result in the wrong size ramp showing up at your door.
But hey, you’re in the right place. At Ramp Champ, we’re Australia’s largest ramp retailer, and this in-depth guide will run you through how to measure for a threshold ramp so you get the right product for your needs.
Measuring The Height Of Your Threshold Ramp
Grab your trusty tape measure and take the height of the door frame or step where you would like the ramp to be installed. Take measurements at both ends of the door, as this will check whether there is any height variation (and if there is, you may need to order a custom ramp, but more on that in a minute).
In an ideal world, the height of the ramp should be exactly the same as the height of your door frame to sit flush and avoid any tripping hazards. So this is where the importance of measuring at eye level comes into play. You see, if your measurements are out - even slightly - it may mean your door is unable to close (which is why some customers choose to order up to 10mm less than their door frame height just to be safe).
Finally, consider whether your door frame has a curve or skirting. In this case, you’ll still need to measure the straight height of the rise (use a level to be sure), as well as the dimensions of the curve or skirting separately. In this situation, you’ll need to order a custom ramp with tailored cutouts so it fits snug.
Measuring The Length Of Your Threshold Ramp
Ramp length (aka ramp depth) refers to how far out the ramp will extend from the door. If maths is your nemesis, then this can get a little confusing. But stick with us as we break it down...
The ideal length of a threshold door ramp will depend on the height you took above - as these two measurements work together to determine a key factor: the gradient (or slope). In Australia, the recommended gradient for a safe threshold ramp is around 1:8 (or less than 8 degrees).
Okay, enough theory. Let’s put it into practice, shall we?
Say the height of your door frame is 35mm. Then, after doing some measuring and shopping around, you decide you want a ramp that is 280mm long. You enter these dimensions into our ramp calculator - and voila! It’s an ideal 7.18 degrees.
Thankfully, all of our stocked ramps are made to a safe gradient (so if you find one that suits your space, you can skip the maths).
But if you need a custom made ramp, always put your dimensions into our ramp calculator before purchasing to ensure the gradient is spot on.
Once you’ve calculated the length you need to get a safe gradient, consider how far out it will extend in your surroundings. Use a tape measure to help you visualise. Does it fit? Is there enough room? Are there any obstructions?
Measuring The Width Of Your Threshold Ramp
Take the width of your door frame or step from left to right. This step is fairly straightforward, but there are a few things to consider as you measure…
You’ll find that many of our pre-made options are suited to a standard door width. But if you’ve got a unique situation, like a wide sliding door, that’s when you’ll need to place a custom order.
When taking the width, you should also consider whether you need winged or tapered edges on the sides. Winged edges are recommended when there will be a lot of space on either side of the ramp. It means the person in the wheelchair can approach the ramp at any angle (and it’s also a safe choice as it minimises the drop off).
On the other hand, if the ramp is going to be positioned in a narrow walkway or hallway, there may not be room for winged edges. In which case, you’ll be better off with a straight-edged ramp.
3 More Things To Consider When Measuring
Do you need a custom ramp?
As you can see, there’s no one-size-fits-all threshold ramp. And that’s why you’ll find a range of different shapes and sizes available.
However, if the ready-made options aren’t quite right for your needs, then you’ll need to order a custom ramp. Many of the custom orders we receive are for sliding door ramps or framed door ramps. If you have either of these, we recommend preparing a sketch of the area (with dimensions) so our team can make the best recommendations.
Custom ramps are also necessary if you don’t have a straight drop at your doorway (for example a curve or skirting). These features will need to be cut out of the ramp, so you must measure these accurately before adding them to your sketch.
For best results, measure twice and order once. Your custom ramp is made especially for you, so take the time to get it right.
Do you need it to be made into sections?
Threshold ramps are incredibly durable. But on the contrary, this means they can be quite heavy.
Consider whether you have someone in your household that can maneuver it. If not, we have the option to order a custom ramp in two or more sections. That way, you can easily piece the ramp together when it arrives at your home (and save your back in the process).
Would you like a custom colour?
All of our Heeve ramps come in a standard charcoal option. If you’d like a different colour to match your home, like sand, terracotta, mocha or grey, these are available for an extra cost. Get in touch with our friendly team for a custom colour quote.
Caring For Your Threshold Ramp
So you’ve carefully measured, ordered and installed your threshold door ramp. Nice one! Now to ensure your ramp lasts well into the future, here are a few pointers...
- Clean your ramp regularly with mild detergent and warm water. Avoid using a pressure washer, strong cleaning chemicals or rough brushes directly on the ramp as this could lead to wear and tear.
- If you’re concerned about slipping, secure the ramp using an adhesive sealant. We recommend Sikaflex which is available at Bunnings.
