How Do I Check My String Spacing?

Last Updated: May 14th, 2021

String Spacing is a time-old question we get asked all the time – 49.2mm, 49.5mm, 50mm, 52mm – which one is right for my guitar? Today, we’ll talk about how to check your string spacing, and answer some basic questions you might have about string spacing in general.


HOW IMPORTANT IS IT?

Pretty important. The pickup’s magnets or pole pieces act as a conductor for the magnetic field of the pickup – and if your strings are not in line with the pole pieces or magnets, you could have a loss in string balance. That said, your strings don’t have to be 100% dead-on with the pole piece. See below for dos and don’ts:

The first two examples will work fine. Most guitar players won’t be able to tell the difference between the two. However, the third example will be noticeable. The string is on the outside of the pole piece, and out of the active magnetic field. You will certainly notice a drop in volume and a general lack of response with this third example.


HOW DO I MEASURE MY STRING SPACING?

Easy. Just have your guitar handy, and a ruler that depicts the millimeter section. You want to measure from the center of each of the outer pole pieces. For example, see below:

How to Measure your Guitar's String Spacing

Each of the above examples is correct ways to measure your string spacing on your guitar. As you can see, each of the humbuckers above is the same physical size, but their spacing is different.

CONVERSION TO INCHES:

  • 49.2mm = 1-15/16″
  • 50mm = 1-31/32″
  • 52mm = 2-1/16″

IF YOU DON’T HAVE A PICKUP IN A GUITAR…

If you don’t have the pickup already installed to see what string spacing you’re trying to replace, measure the strings. Slide the ruler under the strings and see where they fall in the approximate location of the pickup. You will see where the strings fall and can determine your string spacing from there.


MEASURE BOTH PICKUPS.

Measuring both pickups is very important. Depending on your bridge and nut, your pickup spacings may be different. Now that you know how easy it is to measure your String Spacing, take a quick measurement of your bridge pickup as well as your neck pickup. On Fender-style instruments, most of the time you will have a 52mm Bridge and a 50mm neck, as the strings “taper in” the closer you get the headstock.

  1. How can i check and measure fender guitar strings with pickup.

    1. Sam, the guide above lays out the process. Measure the E string to E string over the pickup using a ruler with mm increments, and it should tell you what string spacing is optimal.

  2. Thanks! I needed that. I have an 82 Fullerton tele and the neck pu is so treble and glass like it is just shrill. I want something mello , almost Jazz like . What pu would you recommend?

    1. Hey Monte,

      Check out the Tele Split Blade.

      If you have 250K pots, I would use a Blues Output Tele Neck and you’ll have a warm, dark jazzy tone.

  3. How about pickup height adjustment the lower I go the more weak it gets less highs what would be the best string to pole piece height for your 15% over humbucker
