Choosing Your Slide Model & Sizing Information

Finding a great fitting Silica Sound guitar slide is easy when visiting a guitar store that carries our slides, because you can just try them out…But we offer a variety of slide models and sizes, so ordering online can take a couple extra steps. Please take just a few extra minutes reading this so we can get you the best fitting slide, on the first try.

On this page you should be able to figure out what Model you should get, and your taper sizing if you wish to customize it.

Hopefully our suggestions help. If you end up having difficulty in determining your slide or taper size, feel free to reach out to us HERE

Please download the Slide Model Sizing Guide below for more assistance.

Figure Out Your Slide Model Size

Simply put, our slides come in 2 different wall thicknesses, and there are numerous different diameters in each of the wall thicknesses. We also make slides in 2 lengths: Shorty and Standard.

If you know your ring size for your slide finger this can help with finding the best Model, and that sizing info is on each product page.

1) Do you consider your hands/fingers to be small, medium, or large size?

Small and medium size hands, and ring sizes smaller than 10.5 should check out these model numbers:

Medium Wall: 419, 420, 421

Heavy Wall: 418, 423, 424

No Taper Slides: Extra Small Shorty, Small Shorty, Small, Medium Shorty, Medium

Larger size hands, and ring sizes 10.5-13 should check out these model numbers:

Medium Wall: 421, 422

Heavy Wall: 424, 425, 426, 428

No Taper Slides: Extra Large

2) We strive to produce a fairly consistent product, but the Tapered Interior of each guitar slide does vary a bit as they are each handmade. In general, if the correct Model Size is chosen, the tapered end tends to be a good fit for most people.

Sometimes if they are too tight, or loose, we can work with you to get the right fit.

We can also custom fit the taper and/or the length for you with custom sizing to get you the the perfect fitting slide. See Below.

Please download the Slide Model Sizing Guide below for more assistance.

Custom Slide Sizing

We can create a custom fit for you by controlling the inner diameter of the colored end of the slide, or by cutting the slide to a custom length. Make sure to add this option to your order.

This option is FREE for international orders. Just add it to your order, and we will refund the charge once you place the order. Please take advantage of this so your slide fits well!

Some Tips On Taper Sizing

One easy way to find your Taper Inner Diameter, is to use the downloadable Slide Sizing Guide below. 

The next easiest way is to measure with a pair of calipers. If you have access to a pair of calipers, measure the diameter of your finger where the taper will rest (usually near fingernail or first knuckle).

Alternatively, you can try this method with easy to find materials:

(1) Get a piece of tape, string, piece of paper, or a clothe/flexible tape measure.

2) Wrap it fully around your finger where the taper will rest (usually near fingernail or first knuckle). Make sure its snug but not too tight.

3) Mark off or hold the spot where they first meet, making a circle around your finger.

4) Measure the length of the part that wrapped around your finger where you marked it off. Use millimeters if possible. Be as accurate/precise as possible

(5) Finally, divide your measurement by 3.14 (pi) to get your "Taper Inner Diameter" (example length of 45.5mm / 3.14 = 14.5mm)

Note: In general, Taper Diameters tend to be in the range of approximately 13-17mm.
