When it comes to choosing drawer slides for your cabinetry, the debate between side mount and undermount options can be a bit tricky. Side mount slides are the most common and usually offer a more budget-friendly option. They’re visible from the side and are easy to install. On the other hand, undermount slides, like those available from Incaja, provide a sleek, hidden look and allow for a smoother, quieter operation. The choice often comes down to your preferences for aesthetics and functionality. Let’s dive into the pros and cons of each to help you decide which might be the best fit for your next project!
When it comes to outfitting your drawers with slides, you’ve got two main choices: side mount and undermount. Each type has its own set of benefits and drawbacks, and understanding them can help you make the best decision for your project. Whether you’re remodeling your kitchen, upgrading your office drawers, or just looking for that perfect balance between style and functionality, this guide will help you navigate the pros and cons of each.
What Are Drawer Slides?
Before we jump into the comparison, let’s briefly talk about what drawer slides are and why they matter. Drawer slides, or drawer glides, are mechanisms that allow drawers to open and close smoothly. They come in different styles and are designed to handle various weights and types of usage. The choice between side mount and undermount slides can significantly impact the functionality and look of your drawers.
Side Mount Drawer Slides

What Are They? Side mount drawer slides are attached to the sides of the drawer and the cabinet. They’re the most common type of drawer slide and are usually visible when the drawer is opened.
Pros:
Ease of Installation:
Side mount slides are relatively easy to install. Most come with pre-drilled holes and a straightforward mounting system. This can be a huge advantage if you’re a DIY enthusiast or working with a contractor.
Cost-Effective:
Generally, side mount slides are less expensive than undermount slides. This is partly because they are simpler in design and manufacturing.
Variety of Options:
There’s a wide range of side mount slides available in the market. You can find options that fit various weight capacities and functions, from soft-close mechanisms to heavy-duty slides.
Adjustability:
Many side mount slides offer easy adjustments for alignment and leveling, which can be handy during installation and maintenance.
Cons:
Visibility:
Side mount slides are visible when the drawer is open. While this might not bother everyone, it can detract from a sleek, modern look, especially in high-end cabinetry.
Reduced Drawer Space:
Because side mount slides attach to the sides of the drawer, they can take up valuable drawer space. This can be a consideration if you’re looking to maximize interior space.
Potential for Noise:
Some lower-end side mount slides might be noisier than their undermount counterparts, particularly if they lack features like soft-close mechanisms.
Undermount Drawer Slides

Undermount Drawer Slides provide a sleek, hidden look with smooth, quiet operation, perfect for modern cabinetry. Additionally, if you’re considering side mount drawer slides for your kitchen cabinets, having a comprehensive installation guide can be invaluable. This guide helps with the step-by-step process of mounting the slides on the sides of the drawer and cabinet, ensuring correct alignment and optimal functionality. Whether you choose undermount or side mount, proper installation is key to achieving the best performance and appearance.
What Are They? Undermount drawer slides are attached to the bottom of the drawer and the cabinet. They are hidden when the drawer is closed, providing a clean, modern look.
Pros:
Sleek Appearance:
One of the biggest advantages of undermount slides is their invisibility when the drawer is closed. This creates a clean, streamlined look that’s particularly popular in contemporary and high-end cabinetry.
Smooth Operation:
Undermount slides often provide a smoother and quieter operation compared to side mount slides. Many come with built-in soft-close mechanisms that gently close the drawer, reducing noise and wear over time.
Maximize Drawer Space:
Since undermount slides are hidden beneath the drawer, they don’t take up any additional space inside the drawer itself. This can be a major advantage if you’re trying to maximize storage.
Enhanced Durability:
Higher-end undermount slides are generally robust and can handle heavy loads well. They often feature ball-bearing mechanisms that contribute to their durability and smooth operation.
Cons:
Higher Cost:
Undermount slides tend to be more expensive than side mount slides. This is due to their more complex design and the advanced features they often include.
Installation Complexity:
Installing undermount slides can be more complicated than side mount slides. They require precise measurements and alignment, which might be challenging for DIYers. Professional installation is often recommended.
Limited Adjustability:
While many undermount slides are quite durable and reliable, they typically offer fewer adjustment options compared to side mount slides. This could be a drawback if you need to make precise adjustments during or after installation.
Comparing the Two
When comparing undermount and side mount drawer slides, consider the sleek, hidden look and smooth operation of undermount slides versus the cost-effective and easy-to-install nature of side mount slides. Additionally, drawer fronts come in various styles to complement your cabinetry, including shaker, slab, raised panel, and flat panel designs. Each style offers a unique aesthetic, from the classic elegance of raised panels to the modern simplicity of flat panels, allowing you to customize your cabinets to fit your design preferences.
Aesthetic Considerations: If the visual appearance of your cabinetry is a top priority, undermount slides offer a cleaner look. They’re especially popular in modern designs where the focus is on sleek lines and minimalistic style. On the other hand, side mount slides are more visible but can still be aesthetically pleasing if you choose higher-quality finishes and designs.
Functionality and Smoothness:
Undermount slides generally win out in terms of smoothness and quiet operation. Their soft-close features make them a great choice for high-end kitchens and other spaces where a premium feel is desired. Side mount slides, while functional and reliable, might not match the quiet and smooth operation of undermount models.
Cost vs. Budget:
For budget-conscious projects, side mount slides are often the better choice. They provide good performance at a lower price point and can be a practical solution for many types of cabinetry. If your budget allows for a more premium option, undermount slides offer enhanced features and a more refined look.
Installation and Maintenance:
Side mount slides are typically easier to install and adjust, making them a better choice for DIY projects or when working with less experienced installers. Undermount slides, while offering a sleek appearance, may require professional installation to ensure a perfect fit and operation.

What is the best drawer slide position?
The best drawer slide position depends on the type of slide you’re using. For side mount slides, positioning them correctly on the sides of the drawer and cabinet ensures smooth operation and stability. For undermount slides, precise alignment along the bottom of the drawer and cabinet is crucial for optimal performance and a seamless appearance.
Why are undermount drawer slides so expensive?
Undermount drawer slides are more expensive due to their advanced design, which includes features like hidden mechanisms and smooth, soft-close functionality.

Are undermount slides better than side-mount?
Undermount slides are generally considered better than side mount slides for their sleek, hidden appearance and smoother, quieter operation, especially with soft-close features.

Side mount slides offer a more budget-friendly option and are easier to install, but they are visible and may not provide the same level of smoothness.
Conclusion
Choosing between side mount and undermount drawer slides ultimately depends on your specific needs and preferences. If you’re looking for a cost-effective, easy-to-install option with a variety of styles, side mount slides are a solid choice.
