Going to a jeweler to resize your ring isn’t just costly — it can also damage the ring over time if you need to get it resized again. That’s why DIY ring size adjustments are so useful. Since they’re not permanent, they can work with your changing needs. We love this particular coil wrap ring size adjuster by 5 Stars United because it gives you ultimate flexibility in adjusting the size multiple times around. Just start wrapping the coil around your ring and cut the coil when you feel like you have a good fit. And if you’re on holiday and your fingers swell up a bit, you can simply snip off a coil or two to make it looser. With two available sizes that fit 90% of rings between 1 mm and 5 mm in thickness, you can be sure that you’ll get a good fit every time.

Pros:

• Hypoallergenic, certified TPU silicone
• Won’t distort or damage the ring
• 6 pieces of each size

Cons:

• Can yellow over time

Best Multi-Pack

Let’s be honest: one of the pitfalls of shopping online is getting the item shipped to you in the wrong size. And while we might know our clothing sizes, when it comes to ring sizing, most of us are probably at a loss. If you’re unsure what size ring you wear or what thickness the band is, then don’t waste time with several orders that don’t fit. Instead, go with a multi-pack option like this set by Likimar. With eight different pieces in eight different sizes ranging from XXS to XXXL, you’ll be sure to find the exact adjuster that works for you. Simply snap on the different sizes until you find the one that fits, and save the rest for other rings down the line, or else give a few to a friend who could use a little readjustment, too.

Pros:

• Invisible, clear fit
• Comes with adhesive tape for extra optional support
• Clips on and off easily without damaging the ring

Cons:

• Spacer might slide on the ring when wet

Feramox Invisible Ring Size Adjuster Set

Lowest Profile

Whether you’re wearing a bright statement ring or your grandmother’s wedding ring, you don’t want anything to get in the way of your chosen aesthetic. So having some plastic coils sticking out of the ring for all to see seems less than desirable. That’s why we prefer a low-profile ring size adjuster like the ones in this four-size set by Feramox. With a transparent TPU material that subtly clings onto the side of the ring, the adjustment is pretty much invisible on your fingers. And to truly make you forget that you’re wearing it, the folks at Feramox also made sure the TPU is as soft, flexible, and non-toxic as can be, meaning you won’t feel any irritation on your fingers or notice it when you’re washing your face or hands.

Pros:

• 4 different size options
• Comfortable, secure fit
• Comes with a jewelry cleaning cloth

Cons:

• Adjuster sometimes pops off the ring when putting it on

Most Versatile

The benefit of dropping your ring off at a jeweler is that they’ll treat your ring with the attention it deserves. And while many ring size adjuster sets come in different sizes, some rings don’t adhere to the standard metrics. If you’ve got some funky handmade rings or a band with a wider-than-normal thickness, then you need another option. Here’s where this super versatile kit by Diames comes in. Not only will you get six different sizes of ring adjusters ranging from 3mm to 8mm, but you’ll also get an additional free cutting zone where you can design your own shapes and strip sizes. When you’ve got the shape you need, simply press the cut piece onto the inside of your ring and the adhesive will take care of the rest.

Pros:

• No part of the adjuster is visible outside of the ring
• Comes in three different colors to match your ring
• Soft, scratch-free construction

Cons:

• Poor adhesion if you get the ring wet

Though there are many ring size adjusters out there that’ll give you an invisible fit when the ring is on, you might want the same benefit when the ring is off. If you’re not one to shower or garden in your rings, then you’re likely taking those babies on and off quite often. And seeing a bulky plastic coil or clear spacer on your nice silver or metal polish can be an eyesore you don’t want. Instead, try one of these color matching ring size adjusters by Chuangdi. Choose from a black, white, light grey, or beige color to make sure your ring addition looks as realistic as possible. You’ll get eight sheets of varying size adjusters in all the different colors, all for a couple of bucks cheaper than other brands. Now that sounds like a perfect match to us.

Pros:

• Great cost value
• Breathable adjuster material
• Many sizes and DIY cutting zone in each color

Cons:

• Doesn’t come with instructions for use

Frequently Asked Questions

Why does my ring feel tight?

There are lots of reasons why you may experience swelling in your fingers that causes your rings to feel tight, so it’s important to figure out why it’s happening before you make adjustments to your ring. More long-term changes like weight gain, arthritis, and other health conditions could prompt you to go to a jeweler or find a more permanent adjuster. On the other hand, short-term changes like exercising, having allergies, or even just changes in the weather that change your blood flow only call for temporary adjustments.

How tight should my ring be in general?

The fear of losing your engagement ring may make you prefer a tighter fit. But this can actually cut off circulation to the fingers and even damage your blood flow over time. Experts recommend sizing your ring so that it slides over your knuckle with a little friction and fits snugly below, but without being too tight. When you try to remove it, you should feel some resistance when sliding it back over your knuckle.
