Pedalboard Size Fit Calculator

Pedalboard Size Fit Calculator

Check whether a planned pedalboard physically fits your pedals, patch cable gaps, row spacing, risers, expression pedals, switcher, and power supply footprint before drilling, taping, or rewiring.

🎸 Pedalboard Layout Presets

Load a realistic board scenario, then adjust exact dimensions, cable gaps, row count, top-mounted hardware, and power supply placement to test the fit.

Board And Spacing Inputs
Left-to-right outer board dimension.
Front-to-back outer board dimension.
Rows divide the usable board depth.
Space kept clear near rails, handles, or case lips.
Side jacks usually need more gap than top jacks.
Allows plug exits and comfortable footswitch access.
Used as a safety check against the manual gap.
Front placement protects access to loop switches.
Reserve extra footprint beyond measured hardware.
🎛 Pedal Dimensions And Counts
Typical mini enclosure is about 1.6 x 3.7 in.
Include knob overhang if it affects spacing.
Front-to-back box footprint.
Common single stompbox format.
Boss-style width is roughly 2.9 in.
Include raised footswitch clearance.
Double-wide delays, reverbs, modelers, and loopers.
Use the widest large pedal in the group.
Deep pedals often drive the row depth requirement.
Expression pedals need heel-to-toe depth.
Typical compact expression width.
Full-size volume pedals may be 10 to 11 in deep.
🔌 Switcher, Riser, And Power Footprints
Loop switchers and MIDI controllers consume front width.
Measure including side MIDI or TRS plugs.
Front-row depth used by the switcher.
Risers reserve top footprint but can hide power.
Set 0 if the riser is a full-board rail, not a box.
Reserved depth under the back row.
Top-mounted power competes with pedals.
Use the supply body, not just mounting bracket.
Leave plug exits outside this footprint.

📋 Common Pedal Footprints
Pedal Type Typical Width Typical Depth Fit Note
Mini 1.6 in / 4.1 cm 3.7 in / 9.4 cm Works well in tight single rows, but side plugs can erase the width advantage.
Compact 2.9 in / 7.4 cm 5.1 in / 13.0 cm Good planning default for Boss-style, MXR-style, and common stompbox enclosures.
Double-Wide 4.7 in / 11.9 cm 5.7 in / 14.5 cm Delay, reverb, amp-in-a-box, and loop pedals often need extra hand clearance.
Expression 3.5 in / 8.9 cm 10.0 in / 25.4 cm Depth is usually the constraint; avoid hiding knobs directly behind the treadle.
🧰 Board Size Reference
Board Class Common Size Typical Rows Practical Layout
Nano / rail 14 x 5 in / 35.6 x 12.7 cm 1 row Three to five compact pedals with low-profile cables and no treadle pedal.
Compact two-row 18 x 12 in / 45.7 x 30.5 cm 2 rows Six to eight compact pedals, one small utility, and underside power.
Medium switcher 24 x 12.5 in / 61 x 31.8 cm 2 rows Eight to ten pedals plus a front loop switcher when cable gaps are managed.
Large session 32 x 16 in / 81.3 x 40.6 cm 3 rows Large ambient, MIDI, stereo, or wet-dry rigs with expression and top utilities.
🔀 Spacing And Hardware Checks
Layout Item Minimum Comfortable Why It Matters
Side-jack patch gap 0.35 in / 0.9 cm 0.55-0.85 in / 1.4-2.2 cm Right-angle plugs, jack nuts, and strain relief widen the real footprint.
Top-jack patch gap 0.15 in / 0.4 cm 0.25-0.4 in / 0.6-1.0 cm Top jacks save width but still need cable bend room behind the pedal.
Row-to-row gap 0.75 in / 1.9 cm 1.25-2.0 in / 3.2-5.1 cm Back-row plugs and front-row footswitches need separate operating space.
Case edge clearance 0.25 in / 0.6 cm 0.5-1.0 in / 1.3-2.5 cm Soft cases, handles, hinges, and rails can steal usable perimeter space.
🏚 Preset Layout Examples
Preset Board Size Hardware Mix Main Constraint
Nano Fly Rig 14 x 5 in 3 mini, 2 compact, underside power Single-row width and side plug clearance.
MIDI Switcher Rig 28 x 14 in Switcher, compact pedals, large delay, expression Front controller width and expression depth.
Wet-Dry Stage Board 32 x 16 in Stereo pedals, switcher, top power, riser Buffered surface fill and row-to-row service room.
Acoustic Mini Board 18 x 8 in DI/preamp, tuner, reverb, small switch Keeping the preamp accessible without a second row.
Tip: Measure pedals with the plugs you will actually use. A small enclosure with large pancake plugs can occupy more width than a wider top-jack pedal.
Tip: If the calculator reports a tight fit, reduce the row count before buying a bigger board. Too many shallow rows can make footswitch access worse.

That’s where pedalboard planning comes into play. “I’m going to build this rig out and I’ll just pick up a new pedal.” You come home, there isn’t any room and now what? Cables is all knotted together and that cool little pedal won’t fit. Planning will save your sanity. You won’t have a right angle jack blocking that one foot switch you need in a moment of stage panic.

When you input your measurements into the calculator above, the rest of math happens for you. No more guesswork in the spatial layout department, just some good old fashioned tone. That’s why I think the number one mistake people make is measuring only the metal boxes. That’s the width of the thing. You look at that and think, “okay, that’s all I gotta do.”

Why Planning Your Pedalboard Is Important

No, the devil are in the head end of the cables. In real life, those right-angled plugs sits out a bit from each other, taking up more lateral space then you’d imagine. What the tool does is let you move the space between pedal according to how big your connectors are. And if you’re using giant pancakes, suddenly there’s much more space needed. It is a little detail, but it make all the difference in whether it’ll fit together or if you’re going to end up with some jumble of conflicting strain relief issues.

Measure what goes on floor, not the footprint on the schematic in the manual. Many folks gets burned by depth, especially when working with expression pedals. When looking at a volume treadle, it’s easy to think “I can handle this” until you notice they requires heel-to-toe space that towers over the compact stompbox next to it. Mini/compact/large/expression pedals occupies very different amounts of real estate so the calculator separates them to match. Sure, you may have found a narrow enough expression pedal to slip into a slot, but at ten inches deep, it’s going to gobble up a whole row of space.

Squeeze something else right behind it and now you’re backtracking trying to reach the knobs and switches on your front line units. That’s what the row gap setting is for: ensuring there’s some actualy space for feet to engage and plugs to exit without kicking their neighbor.

But there’s also the invisible stuff. Power supplies and switchers takes up precious space. They’re not magic. A front-facing power brick takes up prime pedal space; an underslung one robs you of depth in useable board length. With the tool, you can turn them off and on and get a sense of their effect on your layout.

Running a MIDI switcher on the front row means everything must wrap around it and will dictate the width of that whole row. That approach result in burying what should of been your go-to tools way out back, which forces you into a contortion act just to hit the loop button.

Included on the page are some usable examples of what would be considered a realistic footprint for different sized boards. And while a nano rail may sound enticing, if you add two pedals with side jacks, it becomes physically impossible to connect them. There are also presets available for things like a full studio rig or a blues club setup. These gives you a place to start tweaking without making the all-too-common mistake of thinking a twenty-four-inch board will hold everything just because it’s twenty-four inches wide.

At its most basic level, planning is a matter of managing limits. You’d like to have this, but it needs to be reliable and accessible. Running the numbers in advance prevents purchasing pedals that won’t fit into your current infrastructure or buying boards that are too small for what you need which can become an expensive habit. It’s a solvable puzzle rather than a potential disaster. Gear set up shouldn’t require brain surgery. Measure twice, cut once. Keep cables happy.
