Average Sizes of Guitar Effects Pedals (With Examples)

Knowing the size of your effects pedals is really important if you are looking to organise a new pedalboard. In this article, I’ll go through each type of pedal and the dimensions with plenty of examples so you know exactly where to go from here.

The Quick Answer

On average, guitar effects pedals are between 4-6 inches in length and 2-4 inches in width. Mini-pedals are typically around 3-4 inches in length and 1.5-2 inches wide. Larger pedals include volume and wah effects which are around 10 x 4″ and multi-effects which have dimensions up to 10 x 18″.

Types of Pedal and Their Dimensions

There are several different types of guitar pedals:

  • Standard (vertical orientation)
  • Wide-style (can be vertical or horizontal orientation)
  • Square
  • Volume and wah pedals
  • Mini pedals
  • Multi-effects
  • Round style

Here is some more information on the dimensions of each type.

Standard Pedals

Most standard guitar effects pedals are around 4.5-5″ in length and 2.5-3″ wide. These types of pedals include most Boss pedals and the Ibanez Tube Screamer.

They usually have 3-4 controls on the front as well as the stomp switch and are oriented vertically.

Wide Style

Wide-style pedals can be orientated either vertically or horizontally. Many Electro-Harmonix pedals are wide-style for example, the Big Muff. These pedals are typically larger than the standard vertical pedals described above.

This style of pedal ranges in size depending on the model, but is usually around 5.5″ x 4″.

Square Pedals

Some effects pedals have a square design and typically take up quite a bit of space on the pedalboard. Some are perfectly square, whilst others are slightly wider or narrow but look almost completely symmetrical.

Square designs are popular with delay and reverb pedals with multiple controls but can be seen with other effects types as well. Typically these pedals are around 4.5 x 4.5″.

Wah and Volume Pedals

Volume and wah pedals are the largest type of pedals and are designed for pedalboards which use two rows, as the vertical edge will take up both rows.

Usually full-size volume and wah pedals are around 10 inches in length and 4 inches wide, hence you need a pretty large pedalboard to place them properly. Alternatively, you can also place them at the side of your board if it’s too small.

Mini Pedals

If you’re struggling for space on your pedalboard, mini effects pedals offer a great solution. They are typically 2/3 or 1/2 the size of the full-size versions.

The exact dimensions depend on the type of pedal. Most rectangular mini pedals are around 3.5 x 1.6 inches. Mini volume and wah pedals are usually around 6 x 3 inches.

PedalHeight x Width (Imperial)Height x Width (Metric)
Ibanez Tube Screamer Mini3.5 x 1.6”8.9 x 4.1 cm

Multi-Effects Pedals

Multi-effects pedals vary in size according to the model and number of effects it contains. Usually, multi-effects pedals with 4-5 effects included are around 5 x 6 inches. However, there are much larger examples which can be around 10 x 18 inches.

Typically, multi-effects pedals are wider than they are all and take up a considerable amount of room on the pedalboard. Albeit, less than if you were to have individual stomp boxes for each effect.

Although rare, some pedals are circular. For example, the Dunlop Fuzz Face.

The full-size Jim Dunlop Classic Fuzz Face is 8 x 7.3″ (20.3 x 18.5 cm) and the Fuzz Face Mini is 3.5 x 3.5″ (8.9 x 8.9 cm). Round-style pedals tend to take up more room on the pedal board than standard rectangular pedals.

How Much Space Do You Need Between Pedals?

As well as considering the size of your effects pedals, you need to factor in the amount of space you need to leave between each pedal when choosing what board size to go for.

This will depend on two things:

  • The cable connection type you are using
  • The location of the input and output jack on the pedal itself

As a general rule, you will need around 2″ between the pedals on your board so that there is enough room for the patch cables. This is best for most pedals which usually have the input and output jacks located on opposite sides of the pedal.

However, there are different types of patch cable on the market which require different spaces, here are some averages.

  • Standard patch cable: 2″
  • Straight coupler: 2″
  • Low-profile patch cable: 1″

If you are struggling to order your pedals in the correct sequence due to the limiting lengths of the patch cable, then try using a DIY cable kit like this Boss Solderless Cable Kit on Amazon. These allow you to customise the length of your connection cables to get the perfect fit.

Some pedals don’t have their jacks located on either side and instead have them on the top or bottom of the pedal. These are great because you can usually place your pedals closer together because the patch cable does not take up any room between the pedals.

Depth Measurement

Most guitar effects pedals have a depth measurement of 1.5-2″. Some exceptions include mini pedals which usually are around 1-1.5″ deep and volume/ wah pedals which are deeper and have a measurement of roughly 2.5″.

Here is a table with some examples.

Average Weight of Guitar Pedals

Guitar effect pedal usually weight between 0.5 and 2 lbs (0.23 and 0.91 kg). For example, most standard Boss pedals weigh 0.81 lbs (0.37 kg). Some pedals may be much heavier, such as multi-effects pedals which may weigh up to 10 lbs (4.5 kg). Mini guitar pedals usually weigh around 0.3 lbs (0.14 kg).
