By William ThompsonJanuary 30, 2026

When it comes to organizing your space, IKEA cabinets offer a wealth of storage solutions. One crucial aspect to consider when planning your cabinet layout is the shelf hole size. Understanding the standard IKEA cabinet shelf hole sizes can help you make the most of your cabinet space and ensure a perfect fit for your shelves.

IKEA cabinets typically use one of two standard shelf hole sizes, which are determined by the cabinet's width. This article will guide you through these sizes, their applications, and how to measure your cabinets for the perfect fit.

Standard IKEA Cabinet Shelf Hole Sizes

IKEA cabinets primarily use two standard shelf hole sizes: 31.5 cm (12.4 inches) and 45 cm (17.7 inches). These sizes correspond to the width of the cabinet and are designed to accommodate a range of shelf depths.

Here's a breakdown of each size and the cabinets they're commonly used in:

31.5 cm (12.4 inches) Shelf Hole Size

The 31.5 cm shelf hole size is used in narrower cabinets, typically those with a width of 30 cm (11.8 inches) or less. This size is ideal for smaller spaces and can be found in cabinets like the IKEA METOD and AKURUM series.

45 cm (17.7 inches) Shelf Hole Size

The 45 cm shelf hole size is used in wider cabinets, usually those with a width of 45 cm (17.7 inches) or more. This size is perfect for larger spaces and can be found in cabinets like the IKEA PAX and BESTÅ series.

Measuring Your Cabinets for Shelves

Before purchasing shelves, it's essential to measure your cabinets to ensure a perfect fit. Here's a simple step-by-step guide:

1. Measure the width of your cabinet. This will determine the shelf hole size you need.

3. Compare your measurements to the IKEA shelf dimensions to find the perfect fit. Keep in mind that shelves should fit snugly but not too tightly to allow for easy removal and replacement.

Choosing the Right Shelf Depth

In addition to the hole size, you'll need to choose the right shelf depth for your cabinet. IKEA offers shelves in various depths, typically ranging from 30 cm to 45 cm (11.8 inches to 17.7 inches). The ideal depth depends on your storage needs and the items you'll be placing on the shelves.

For example, lighter items like books, dishes, or canned goods can be stored on shallower shelves, while heavier or bulkier items may require deeper shelves for better support and stability.

With the right shelf hole size and depth, you can create a functional and organized storage solution in your IKEA cabinets. Happy organizing!
