A patch that fits properly seals out light, holds without pressure, and disappears from your mind once it is on. A patch that does not fit slips, gaps, or digs in all day. Getting a custom fit eye patch starts with a few simple measurements. Here is what to measure and how.
Why fit matters more than size labels
Faces differ in ways that small, medium, and large cannot fully capture. Two people with the same hat size can need very different patches. Measuring your own face, rather than guessing from a label, is the surest way to get a patch that sits cleanly the first time.
What you need
A soft tailor’s tape measure is ideal. If you only have a rigid ruler, use a length of string, mark it, then measure the string against the ruler. Work in front of a mirror in good light, and take each measurement twice to be sure.
The measurements that matter
- Socket height and width. Measure the eye opening from brow bone to cheekbone, and from the bridge of the nose to the outer corner. This tells you the coverage the patch needs.
- Bridge to ear. Measure from the side of the nose, across the eye, to the top of the ear. This sets how the patch and strap sit across the face.
- Head circumference. Run the tape around your head where the strap will sit, just above the ears. This sets the strap length.
Turn measurements into a good fit
With those numbers you can judge whether a given patch will cover your socket without gapping, and set the strap to hold without cutting in. If your measurements fall between standard sizes, an adjustable patch takes out the guesswork. Our Universal patch is built for this, with a strap you can set precisely to the head measurement you took.
Check the fit once it arrives
When you first put the patch on, look for even contact around the whole rim with no light leaking in at the nose or cheek. The centre should not press on the eye. The strap should hold the patch steady when you turn your head, without leaving a deep mark. If all three are true, you have a proper fit.
Measure once, carefully, and you avoid the usual cycle of returns and adjustments. To start, take a look at our range of eye patches and match your measurements to the right model.
Adjustable versus made to measure
Once you have your measurements, you have two ways to get a good fit. An adjustable patch lets you set the strap, and sometimes the angle, yourself, which suits most people and removes the guesswork if you fall between sizes. A made to measure patch is built to your figures from the start, which is worth it if your face is well outside the average or you want the cleanest possible seal. Either way, accurate measurements are what make it work, so take them twice and in good light. If your current patch slips or gaps despite a decent fit, our guide on keeping a patch from slipping covers the quick fixes.
Fit is only part of the picture. When you are ready to compare models, the checklist in our buyer’s guide walks through material, shape, and strap alongside sizing.
Frequently asked questions
How do I measure for an eye patch?
Measure your eye socket from brow bone to cheekbone and from the nose to the outer corner, the distance from the side of your nose across the eye to your ear, and your head circumference where the strap sits. Take each measurement twice in good light.
What do I need to measure my face for a patch?
A soft tape measure is ideal. If you only have a rigid ruler, use a length of string, mark it, then measure the string against the ruler. Work in front of a mirror with good lighting.
Is an adjustable eye patch as good as a custom one?
For most people, yes. An adjustable strap and a shape offered in more than one size cover the vast majority of faces. A fully made to measure patch is worth it mainly if your face is well outside average or you want the tightest light seal.
How do I know an eye patch fits correctly?
Look for even contact around the whole rim with no light leaking at the nose or cheek, a centre that does not press on the eye, and a strap that holds the patch steady without leaving a deep mark. If all three are true, the fit is right.
What if I am between eye patch sizes?
Choose the adjustable option. A fixed size between your measurements will either gap or press, while an adjustable strap lets you set it exactly, which is the simplest way to avoid returns.
