How to pick the right Eurorack size
Choosing the right modular synthesizer rack begins with measuring your available space and estimating your signal flow needs. Eurorack modules are standardized by width in "HP" (Horizontal Pitch), where 1 HP equals 0.5 inches or 12.7mm. Your physical footprint is determined by the total HP count, which typically ranges from 60 HP for portable, compact setups to 120 HP or more for large, stationary studio systems.
When planning your 2026 setup, consider the physical constraints of your desk or case. A 60 HP rack, such as those found in Intellijel's compact cases, offers a manageable footprint for essential oscillators, filters, and sequencers. However, as your patching complexity grows, you will quickly outgrow these smaller formats. A 120 HP rack, like the Doepfer A-100 series standard, provides the necessary depth and width to accommodate larger modules, complex audio routing, and additional power distribution without excessive cable clutter.
It is also critical to account for future expansion. Modular synthesis is an evolving hobby; new modules are released constantly, and your sound design requirements will shift. A good rule of thumb is to leave at least 20% spare space in your rack for future modules and cable management. This buffer prevents the frustration of having to rebuild your entire system just to add a single new effect or modulation source.
Modern rack designs in 2026 also emphasize material quality and durability. Brands like 4ms and Intellijel have updated their chassis designs to use thicker aluminum and improved powder-coating finishes, which resist wear and tear better than older models. This is particularly important if you plan to transport your rack for live performances or studio sessions. Check the specific HP capacity and build quality of each rack model to ensure it aligns with your long-term modular journey.

Clean power keeps your modular rig stable
Clean power is the invisible foundation of any Eurorack system. Unlike standard audio gear, modular synthesizers draw fluctuating current as oscillators and filters engage. A weak or noisy power supply causes voltage drops, leading to glitchy sequencing, unwanted clicks, or modules resetting unexpectedly. In 2026, the focus has shifted toward efficiency and thermal management, with manufacturers adopting better heat dissipation materials and more precise voltage regulation to handle the demands of modern, high-current modules.
The Intellijel Power Module 2 remains a top choice for its compact footprint and reliable 12V/15V distribution.

Common modular rack: what to check next
Buying a modular synthesizer rack involves more than just measuring width. The depth of your case dictates which modules fit, and the material affects both durability and sound. Here are the most frequent questions buyers ask when planning a 2026 Eurorack setup.
Do I need a 20hp or 42hp rack?
The standard Eurorack format is 42hp wide (19.02 inches), which accommodates most mainstream cases like the Intellijel Palette or Doepfer A-100. If you are building a compact travel rig, a 20hp or 32hp micro-rack might suffice, but you will be limited to smaller modules. Always check the internal depth as well; 55mm is standard, but some high-current modules require 75mm or more.
Are wooden racks better than aluminum?
Aluminum cases, such as those from 4ms or Intellijel, are lightweight and durable, making them ideal for touring musicians. Wooden racks, often built by custom luthiers or brands like Make Noise, offer a warmer aesthetic and can reduce resonance, though they are heavier. For 2026, many manufacturers are using recycled aluminum or sustainable wood composites to reduce environmental impact without sacrificing structural integrity.
How do I ship my modular system safely?
Shipping modular synthesizers requires careful packaging to prevent case damage and module dislodging. Use anti-static bags for all modules and bubble wrap the entire rack. Never ship a case with modules installed unless they are securely screwed in and the case is padded internally. For international shipping, check voltage compatibility; most Eurorack power supplies are 100-240V, but some older or specialized units may require a transformer.
