Undermount vs. Side Mount Drawer Slides- Which One is the Best?

If you are planning to build or renovate your cabinets, one crucial decision you will have to make is choosing the right drawer slides. Drawer slides are mechanisms that enable drawers to slide in and out of their housing easily. 

There are two main types of drawer slides, undermount, and side mount, and selecting the right one can have a significant impact on the functionality, durability, and appearance of your cabinets.

Undermount vs. Side Mount Drawer Slides- Which One is the Best? 1


1. Undermount drawer slide

Undermount drawer slides attach to the underside of the drawer, while side mount drawer slides attach to the side of the drawer. The choice between under-mount and side-mount drawer slides will depend on the type of cabinet you have, the weight of the drawer, the amount of available space, and your personal preferences.

Undermount drawer slides are hidden from view when the drawer is closed, giving the cabinet a sleek and modern look. They are also more durable than side-mount drawer slides and can accommodate heavier loads. Since the drawer sits directly on the slide, under-mount drawer slides offer better stability and less side-to-side movement. They also allow for full extension, which means the entire drawer can be accessed, making it easier to store and retrieve items.

But at the same time, undermount drawer slides are typically more expensive than side-mount drawer slides. They also require more skill and effort to install since they must be accurately aligned with the cabinet housing. If the drawer is overloaded, the undermount drawer slide can become damaged, leading to reduced functionality or complete failure.

2. Side Mount Drawer Slides           

Side mount drawer slides are easier to install, making them ideal for DIY projects. They are also more affordable than under-mount drawer slides, and some models have a higher weight capacity than their under-mount counterparts. Side mount drawer slides have a larger range of available lengths, making them more versatile in terms of drawer size. Additionally, side mount drawer slides are typically easier to remove and replace if they become damaged.


However, side-mount drawer slides are not as durable as under-mount drawer slides and can wear out over time. They are also visible from the outside of the cabinet, which can detract from the overall appearance of the cabinet. They do not offer full extension, which can make it harder to access items stored in the back of the drawer.

Weight Capacity

Undermount drawer slides typically have a higher weight capacity than side mount drawer slides. They can handle heavier loads and are suitable for larger and wider drawers. On the other hand, side mount drawer slides are better suited for smaller and lighter drawers.


Aesthetics Of Undermount Drawer Slides 

Undermount drawer slides is their sleek and seamless appearance. With no visible hardware or metal, the focus remains on the drawer itself, creating a clean and modern look. Side mount drawer slides, on the other hand, are attached to the sides of the drawer, making them visible when the drawer is opened. This can interrupt the flow and smoothness of the overall design.


Self-Closing Option

Many undermount drawer slides also come with a self-closing option, which allows you to simply push the drawer a little, and it will close smoothly in a slow and steady manner. This feature can add an extra level of convenience and sophistication to your cabinets.



Undermount drawer slides have the advantage of being easily adjustable without requiring any tools. Side mount drawer slides, on the other hand, typically require you to remove the drawer from the cabinet and use a screwdriver to make any necessary adjustments. This can be a time-consuming and frustrating process, especially if you need to adjust the slide up and down or side to side.



hygiene is an important consideration when it comes to drawer slides. Undermount drawer slides stay underneath the drawer of your cabinet, which means they are less exposed to dust and pollution. This makes them easier to clean and maintain than side mount drawer slides, which can collect dust and grime over time. If spills occur inside your cabinet drawer, undermount slides can be easily removed and cleaned, while side mount slides require cleaning in place.
