“The Difference Between Jumbo and Medium Jumbo Frets –

Jumbo and Medium Jumbo frets are found on many electric guitars from brands like Fender, Gibson and Ibanez, but what’s the difference between them?

In this article, I’ll explain everything you need to know about the difference between these two beam sizes

Beam size refers to the width and height of the beam wire

Fret size affects playability and most players will have a preference for one fret size over another

Two of the most popular sizes are Jumbo and Medium Jumbo

Here are the measurements for the Dunlop Medium Jumbo and Jumbo frets

The medium jumbo frets are only 0036″ tall, while the jumbo frets are 0055″ tall

This means that the medium jumbo frets are just over 50% taller than the jumbo frets or 0019″

Medium jumbo and jumbo frets are very similar in width

Jumbo frets are only 0004″ wider than medium jumbo frets, which equates to a 4% difference

So when comparing medium jumbo and jumbo frets, the difference in height is the only thing we really need to look at

Since the medium jumbo frets are not very tall, you will feel more of the wood of the fretboard when playing compared to the jumbo frets which are much taller, meaning you will feel more of the fret itself than the wood

Longer jumbo frets tend to be easier for most players to upset compared to shorter medium jumbo frets

This is one of the reasons why jumbo frets are found on many metal and chopped guitars as they make it easier to pull in/out

Taller jumbo frets are also better for string bending compared to shorter medium jumbo frets

This is because there is less friction between the fretboard and the fingers with jumbo frets

However, because there is more space between the fretboard and the strings with jumbo frets, there is a greater chance that the notes will be pushed out of harmony if too much finger pressure is applied

Beam size has little effect on the tone of electric and acoustic guitars

On the other hand, the mid-jumbo frets sound a bit clearer and have more definition

However, beam size has very little effect on the tone of an electric guitar, especially when comparing these two sizes that are really different in height

Once you turn on the guitar, and especially if it’s in the mix, you won’t find many players who can hear the difference between the two

I would highly recommend going down to your local guitar shop and trying out some medium jumbo and jumbo necks

Try and make sure the other door parameters are similar (profile, width, bit radius) otherwise you won’t get a good comparison

Personally, I prefer the feel of medium jumbo frets and find the jumbo frets a bit too tall for me

I prefer my fingers to be more in contact with the fretboard

However, many players prefer jumbo frets
