Too-tight rings are annoying and uncomfortable. Luckily, if you have a simple ring without any stones in it, you can stretch it at home with the help of some simple tools. Start by finding the size of the ring, as well as the size of the finger you want to wear it on. To stretch the ring, you’ll either need to use a ring stretcher tool or a steel mandrel, which is a tapered rod that jewelers use for sizing rings. Once you have the tools, stretching your ring is an easy task and you’ll have a more comfortable ring in no time.

Using a Ring Stretcher

  1. Slide the hollow bottom of your ring stretcher into its base.
  2. Place your ring around the hollow mandrel and insert the pin.
  3. Use a rawhide hammer to gentle hammer the top of the stretcher.
  4. Put on your ring to check if the size is correct. If not, hammer your ring again.

  1. If you stretch a ring with stones on it at home, the stones might pop off. If your ring has a pattern engraved in it, the pattern might become misshapen as you stretch the ring. [1]
    • If you can’t stretch your ring at home, consider getting it done professionally be a jeweler.
  2. A ring mandrel is a tapered, metal rod with ring sizes marked on it that you can use to measure ring sizes. You can buy one at a hardware store or online. Simply slide the ring onto the mandrel. The bottom of the ring will line up with a marked number on the mandrel. [2]
    • Consider getting a steel mandrel, because they are more versatile, and you can even use one to stretch your ring.

  3. Figure out your ring size using a ring sizer. A ring sizer looks a bit like a ring of keys, except instead of keys, there are a metal rings in order of their size. They often come with a ring mandrel when you buy it. Try on the rings until you find the one that fits on your finger. The ring should slide on fairly easily and be a little hard to take off. [3] [4]
    • Note that it’s impossible to have a ring fit perfectly, because our fingers change size throughout the day based on temperature, exercise, and time of day. [5]
    • A ring should fit snugly without making your finger bulge around it or leaving indent marks.
  4. with paper and a conversion chart as an alternative. If you don’t have access to a ring sizer, you can also use measure around your finger with a strip of paper and mark the paper where it wraps. Then, measure the length of the paper with a ruler. Finding a conversion chart online to convert the measurement to ring size. [6]
    • Make sure you find a conversion chart for your country, because different countries have different ring measurement systems.
    • Fingers get smaller in the cold, so make sure you are warm before you size your finger.
  5. If the difference between the current ring and the size you want it to be is more than ½ size, you should probably see the jeweler to help you. When you stretch a ring, you are making the metal thinner, so if you stretch it too much it will weaken the ring and could even break it. [7]
    • Jewelers have other methods for enlarging rings that don’t thin the metal, such as cutting the ring open and adding metal. [8]

Ring Stretcher

  1. Make sure you are working on a firm, hard surface like a concrete floor or sturdy metal table. Ring stretchers come with three basic parts: a nylon base which holds the tool and dampens hammering impact, a slotted, hollow mandrel, and the top pin, which you will hammer on. Slide the slotted, hollow part into the nylon base.
  2. The ring should fit snugly around the metal surface of the hollow bottom part of the stretcher. Then, slide the top pin into the hollow interior of the bottom piece.
    • The top pin is the part you will hammer, and it will push open the slotted part so that it evenly opens up your ring.
  3. A rawhide hammer will be more gentle than a metal hammer. Hammer lightly, because you don’t want to overstretch your ring. It’s best to use many light taps, rather than a few hard taps, so that you can slowly expand the ring and you don’t accidentally enlarge it too much.
    • You should be able to see the bottom of the ring stretcher opening slightly as you tap.
  4. Take the ring out of the stretcher, and try it on your finger. You can also measure the new size on a ring mandrel. If it is the right size, you’re done. If it’s not wide enough, put it back on the ring stretcher and give it a few more taps.
    • Remember, it’s easy to stretch your ring, but harder to shrink it , so stretch it in small increments.

Ring Mandrel

  1. You’ll need a steel mandrel, not a plastic one, because it needs to be able to withstand your hammer taps. Put the ring on the mandrel at the narrow end, and slide it down as far as it goes. Don’t force it on, because you’ll be pushing it down further with a hammer to stretch it. Right now, it can just sit in its natural position. [9]
    • If you want a slightly more secure set up, get a bench pin which can secure your steel mandrel to your table, but you can also just hold the mandrel.
  2. Tap the ring with the hammer at the top of the ring, not the side. Rotate the ring as you tap it, so that you are hitting all sides evenly. Stop when you’ve tapped a full circle around the ring. Use the same amount of pressure for each tap, so that your ring stays even. [10]
    • Your hammer strokes should be parallel with the mandrel, so that you’re gently pushing the ring further down toward the thicker end of the mandrel.
    • Don’t use a metal hammer for this, because it may dent and mar the surface of your ring.
  3. Since the mandrel is tapered, if you only tap on one side of the ring, it will come out uneven. To adjust for this, remove the ring from the steel mandrel after you’ve tapped all the way around. Then, tap the top of the ring with the rawhide hammer, just as you did before. [11]
    • Stop when you’ve gone all the way around once.
  4. You may have to do this several times. Check how far the ring has slid down the mandrel after each round of hammering. Remember, you can always stretch it more, but it’s difficult to shrink a ring at home.
    • If your ring is a little bit stuck on the mandrel when you’re trying to remove it, just tap it lightly in the other direction with your hammer until it loosens. [12]
