What size belt to buy for my turntable?

Step by step instructions to Measure your Belt Length

Stop! Just stop right there!

There are numerous models of turntables in the world. 

To start with, let us discuss belt lengths. They are usually indicated in mm utilizing the circumference (for example, the absolute length of the belt).

Kindly make sure that these belts won’t work with decks with round belts & are flat, i.e., Michell or Rega.

If the deck is not found anywhere, you can buy a custom length for no extra charge from the multiple websites.

To select the correct size belt , utilize one of these two techniques.

Method 1 

You can take your current belt & lay it flat against a ruler, and then calculate the length, followed by doubling the estimation so that this will provide you the correct measure of the circumference.

Method 2 

  • You can utilize a pulley & length of string or string wrapped around the sub-platter.
  • Calculate the string length to give the circumference of the belt, for example, the total length of the belt.
  • For an update over regular flat neoprene belts, utilize a rare material that delivers the correct outputs of any material you have used (and there are a ton).
  • Those belts might not just be striking in delivering better sound, particularly in more profound and progressively exact bass. Still, they also wipe out static issues that occasionally happen on decks.
  • And for such sort of unique material, search different websites suitable to you.

Three simple methods that are strictly related to the belt are:

So, what are these numerical portions of the belt part? Here, these portions tell us about the total circumference in inches.

1. Complete intact belt, however, extended

Determine the length of the entire belt along a ruler (in inches), subsequently twofold that estimation. Reduce 5%-10% to make up for extending.

2. Broken belt

On the off chance that your belt is broken at a single spot, it is anything but difficult to measure – lay it close by a ruler and measure its length in inches. Reduce 5%-10% to make up for the extending of the old belt.

3. An old belt makes noise or Missing belt

  • First, pull the string very tight and measure the belt path(fold the string over the pulleys just as the belt would go).
  • If the belt tends to be making noise & is unmeasurable, the part where it overlaps, slice through the string.
  • Remove the ends & afterward calculate the length of the string (in inches) that was folded over the pulleys, which is the real length of the belt path.
  • Reduce 5% to 10% to make up for extending. Request a belt with the subsequent length.
  •  The FBS or the SBS series (thin square belt) are considered best for Cassette decks.
  • The SBM series size belt is generally used in Disc and DVD players.
  • VCRs use the SBL size belt as a rule, & if the belt is a flat one, the FBM size comes into play.


  • Most turntables nowadays are either belt drive or direct drive.
  • Every so often, belt drive turntables require turntable belt substitution or replacement.
  • This time frame can fluctuate from a couple of years to 20 years or all the more relying upon the belt’s quality, turntable utility, and other natural conditions.
  • Also, according to the basic idea, an average turntable belt for audiophile use will last 3-5 years before it loses its worth. Low-quality belts on low-quality turntables work somewhat more, as the customers’ can’t decipher easily.
  • Most modern belts are made of urethane or a mix incorporating urethane.
