Selecting the right size of curtain hooks might seem like a small decision, but it significantly impacts the functionality and aesthetic of your window treatments. This guide helps you understand the various sizes of curtain hooks and how to choose the perfect ones for your curtains.
Curtain hooks, also known as curtain rings or eyelet hooks, come in different sizes to accommodate varying curtain weights and rod diameters. They are typically measured in millimeters (mm) and are designed to fit specific rod sizes.

Understanding Curtain Hook Sizes
Curtain hooks are primarily sized based on the diameter of the curtain rod they are meant to hang from. The size of the hook determines how securely it stays on the rod and how much weight it can support.
Hook sizes usually range from 16mm to 35mm, catering to various rod diameters and curtain weights. Here’s a breakdown of different hook sizes and their corresponding uses:
Small Curtain Hooks (16mm to 25mm)
Small curtain hooks are ideal for light to medium-weight curtains and shorter curtain rods. They are perfect for valances, café curtains, and tiered curtains. These hooks typically fit rods measuring from 16mm to 25mm in diameter.
Small hooks are also useful when hanging curtains on tension rods. Since tension rods have a limited weight-bearing capacity, using smaller hooks helps distribute the weight more evenly, preventing the rod from sagging.

Medium Curtain Hooks (28mm to 32mm)
Medium-sized curtain hooks, ranging from 28mm to 32mm, are suitable for medium-weight curtains and standard-sized curtain rods. They are a versatile option for ensuite rooms, bedrooms, and living rooms, and can accommodate a wide range of rod diameters.
These hooks are perfect for gathered or tab-top curtains, as they provide ample space for the fabric to gather, creating a fuller, more voluminous look.
Choosing the Right Hook Size for Your Curtain Rod
Before selecting curtain hooks, it’s crucial to measure your curtain rod’s diameter. This measurement will help determine the appropriate hook size to ensure a secure fit. Here’s a simple guide to matching hook sizes with rod diameters:

Rod Diameter Hook Size
- 16-20mm: 16-20mm hooks
- 22-25mm: 20-25mm hooks
- 26-30mm: 26-30mm hooks
- 31-35mm: 30-35mm hooks
Matching Hook Size with Curtain Weight
Hook size is also crucial in supporting the weight of your curtains. Heavier fabrics, like velvet or tartan, require larger hooks that can bear more weight. Conversely, lighter fabrics, such as voiles or sheers, can be hung using smaller hooks.
As a general rule, choose hooks that are slightly larger than your rod’s diameter. This provides additional support and prevents the hooks from wobbling or slipping off the rod.
Compatible Hook and Rod Shapes
Curtain hooks come in various shapes − round, flat, or decorative − designed to fit specific rod shapes. Before purchasing, ensure that the hook’s shape is compatible with your rod’s shape. Round hooks are versatile and fit most rod shapes, while flat hooks are ideal for thin, flat, or Burlingtonian rods.

In conclusion, selecting the right-sized curtain hooks is crucial for creating an aesthetically pleasing and functional window treatment. With this guide, you can easily choose the perfect hooks for your curtains, ensuring they hang securely and beautifully. Don’t forget to measure your rod’s diameter and consider the weight of your curtains to make an informed decision.
