The Complete Guide to Storing Vallejo Paints: Every Bottle Size and Rack Option
Vallejo 17ml dropper bottles fit standard 26mm rack slots — the most common format available. The 72ml airbrush bottles need wider slots or separate storage. Complete guide to every Vallejo range and rack compatibility.
Dropper bottle: a squeeze bottle with a narrow dispensing tip, typically 17ml for Vallejo Game Color and Model Color ranges. The 26mm diameter is the global standard for modular paint storage systems, making these bottles compatible with PROSCALE’s 26mm-slot racks without modification.
Airbrush bottle: a wide-mouth 72ml container used for Vallejo’s thinned, air-atomized paint lines. These bottles require 35mm+ slots or dedicated wall space due to their diameter — they block access to smaller droppers if mixed in the same rack.
VALLEJO PRODUCT LINE OVERVIEW AND BOTTLE FORMATS
Vallejo makes ten distinct paint ranges, each designed for different mediums and applications. The two primary bottle formats — 17ml droppers and 72ml airbrush containers — create the storage challenge that defines any Vallejo-specific organization strategy.
The 17ml dropper bottles are the workhorse of the Vallejo ecosystem. Game Color, Model Color, Model Air (premixed for airbrush), Metal Color, Liquid Metal, and Xpress Color all use the same 26mm diameter container. A painter with one Vallejo range can confidently purchase a standard modular rack designed for dropper bottles. However, many serious Vallejo painters own multiple ranges simultaneously — Game Color for miniature painting, Model Color for detail work, and Model Air premixed for speed on primed surfaces. A single 26mm-slot rack accommodates all of these without any modification or compromise.
The 72ml airbrush bottles represent Vallejo’s full-strength product for professional airbrush users. These are wider, shorter, and incompatible with standard dropper racks. Painters using both 17ml droppers and 72ml bottles face a choice: segregate them into two racks, use a rack with adjustable or mixed-diameter slots, or store the airbrush bottles horizontally on a dedicated shelf. Most established Vallejo painters opt for segregation — it simplifies inventory visibility and reduces the cognitive load of scanning a mixed-format rack.

17ML DROPPER BOTTLE COMPATIBILITY AND RACK SELECTION
The 17ml Vallejo dropper is engineered to 26mm diameter with a 5mm dispensing tip. PROSCALE’s standard 26mm slots accommodate this format without friction or play. Unlike Citadel’s 32mm pots, which require explicit 33mm+ slots, Vallejo droppers are forgiving — they fit any rack designed for miniature paint bottles in the 25–27mm range. This makes Vallejo the de facto standard for new painters selecting their first rack.
Three organizing strategies emerge from this compatibility advantage. The first strategy — organize by color family — clusters reds with oranges, yellows with earth tones, and cool colors together. This method reduces search time when color-matching and works equally well for Game Color and Model Color, since both brands use the same color naming convention (“Deep Orange,” “Metal Blue”). A painter with 80 mixed Vallejo bottles in this system can identify a needed shade in under ten seconds of shelf scanning. The second strategy — organize by range — segregates Game Color, Model Color, Model Air, and Metallic sections. This works better for painters who batch-paint by range rather than by project. If a painter is using Model Air for speed-priming an entire army, having all Model Air bottles in sequence eliminates the need to switch racks. The third strategy — organize by project — groups bottles for specific models or painting campaigns. A Warhammer Space Marine army might have five bottles of red shades, two metallic silvers, one wash, and a shade — all together in a dedicated slot sequence. Project organization is effective for one-model-at-a-time painters but less practical for painters managing multiple simultaneous projects.
72ML AIRBRUSH BOTTLE SEGREGATION AND STORAGE SOLUTIONS
Vallejo’s 72ml airbrush bottles are 39mm in diameter — substantially wider than the 26mm droppers. Mixing them in a single 26mm rack creates a cascading problem. The bottle sits too deep in the slot, partially hidden. The weight of a 72ml bottle applies pressure to adjacent 26mm droppers, potentially crushing them if they’re thin-walled plastic. And visually, the rack becomes inconsistent — some bottles fully visible, others buried — which defeats the purpose of wall-mounted storage.
The first solution is complete segregation. A dedicated 35mm+ slot rack holds all 72ml bottles vertically on one wall or shelf, while 26mm droppers occupy another. This requires space but creates absolute clarity about inventory. A painter who owns three types of 72ml airbrush bottles (standard, thinner, base coat) can organize them within the same 35mm rack and know exactly how much of each they have.
The second solution is horizontal storage on a shelf or bin above the dropper rack. 72ml bottles are stable when laid flat — they don’t tip or roll like dropper bottles do — so a simple wooden ledge or deep shelf suffices. This saves wall space and is practical for painters who use the 72ml bottles occasionally rather than daily. The bottles remain visible from the side, and inventory checks are still fast.
The third solution is compartmentalization within a larger system. PROSCALE modular racks can expand to include both 26mm and 35mm+ slot sections in a single wall installation. A painter with 40 dropper bottles and 8 airbrush bottles can dedicate the bottom row to 35mm slots and the upper rows to 26mm slots. This creates visual hierarchy — the wider bottles ground the system, the narrower ones densify above. It also accommodates future growth without requiring a second rack.

VALLEJO BOTTLE DIMENSIONS AND SLOT COMPATIBILITY
| Vallejo Range | Volume | Diameter | Required Slot | Compatible PROSCALE Rack |
|---|---|---|---|---|
| Game Color | 17ml | 26mm | 26mm | Yes, all 26mm racks |
| Model Color | 17ml | 26mm | 26mm | Yes, all 26mm racks |
| Model Air | 17ml | 26mm | 26mm | Yes, all 26mm racks |
| Metal Color | 17ml | 26mm | 26mm | Yes, all 26mm racks |
| Liquid Metal | 17ml | 26mm | 26mm | Yes, all 26mm racks |
| Xpress Color | 17ml | 26mm | 26mm | Yes, all 26mm racks |
| Airbrush (72ml) | 72ml | 39mm | 35mm+ | Requires dedicated section or shelf |
| Panzer Aces | 17ml | 26mm | 26mm | Yes, all 26mm racks |
| Game Air | 17ml | 26mm | 26mm | Yes, all 26mm racks |
The 26mm standard is the global baseline for dropper bottle racks. All Vallejo dropper ranges — every one in production — share this diameter. A painter can build a Vallejo-focused system entirely around 26mm-slot configurations and achieve perfect fit across the entire product range, with one exception: the 72ml airbrush bottles require 35mm+ slots or separate storage.
VALLEJO RANGE-SPECIFIC ORGANIZATION AND COLLECTION GROWTH
Vallejo’s naming conventions and color philosophies differ across its ranges. Understanding these differences prevents organization confusion as collections grow.
Game Color is the entry-level range, optimized for board games and casual miniature painters. The palette is curated around core painting needs — primary reds, blues, yellows, plus earth tones, metallics, and foundation colors. A complete Game Color collection is approximately 40–50 bottles. Organization by color family is intuitive here because the range has no redundant colors. If a painter adds to Game Color over time, they’re typically adding expansion sets (special metallic sets, weather effects) rather than duplicates.
Model Color is the professional workhorse, used by competition painters and model kit builders. The palette is extensive — 200+ colors available, with high specialization (e.g., four distinct shades of russian green for Cold War Soviet vehicles). A painter starting with Model Color might begin with a curated starter set (70–100 bottles) and then expand by project or specific model. Organization by color family remains manageable up to about 120 bottles. Beyond that, sub-organizing by hue (all reds together, then organized light-to-dark within reds) becomes necessary. A Model Color collection grown to completionist levels (150+ bottles) typically requires a dedicated wall system or multiple racks.
Model Air is Vallejo’s premixed airbrush range — thinner and formulated to flow through airbrush nozzles without clogging. These 17ml bottles use the same 26mm format as dropper variants, but the paint is chemically distinct. Model Air bottles should be stored separately from Game Color and Model Color to avoid accidentally using unpredictable (thinned) paint for brush painting. In a PROSCALE 26mm system, this means one section for Model Air, a separate section for Model Color. A painter who owns both ranges typically dedicates 10–15 bottles to Model Air (one per prime color, one per accent color) and keeps them visually isolated.
Metal Color and Liquid Metal are specialized metallics with different working properties than standard acrylics. Liquid Metal in particular — Vallejo’s metallic lacquer — is a different medium entirely. Both ranges are small (10–20 bottles per painter maximum) and are best stored separately from the main collection to prevent accidental misapplication. A dedicated 26mm slot section or small secondary rack works well.
Xpress Color is Vallejo’s fastest-drying range, formulated for speed-painting competition miniatures. The palette is tight — 40 colors that cover the most common competition scenarios. Many painters who use Xpress Color also use Game Color or Model Color for detail work, so a mixed-range rack is common. Organization by color family works as well as for Game Color.

COLLECTION SIZE BENCHMARKS AND STORAGE CAPACITY PLANNING
The question “how big should my paint rack be?” has a direct answer when organized by Vallejo range. A painter’s growth arc typically follows a predictable pattern.
The starter collection — one Game Color set plus a few impulse purchases — runs 30–50 bottles. This fits in a single PROSCALE 26mm rack with 60 slots. The painter has room for growth without crowding, and the visual density feels professional without appearing obsessive.
The working collection — a painter actively engaged in miniature painting or modeling — typically reaches 80–120 bottles. This is the sweet spot where a painter owns core Game Color plus significant Model Color depth. A 120-slot rack accommodates this comfortably. At this scale, organization by color family becomes important for speed.
The comprehensive collection — a painter who paints daily or maintains multiple simultaneous projects — reaches 150–250 bottles. This requires two racks or one very large wall installation. A painter at this level typically owns multiple Vallejo ranges (Game Color, Model Color, Model Air, Metallics) and organizes by range first, then by color family within ranges.
The completionist collection — painters who own Vallejo colors spanning 250+ bottles — have effectively committed to Vallejo as their primary paint system. These painters typically dedicate an entire wall to paint storage and may use a combination of modular racks, custom shelving, or tiered systems to maintain visibility.
Understanding where a painter falls on this spectrum helps guide rack purchases. Buying too small means outgrowing the system in six months and requiring an expensive second installation. Buying too large creates the psychological burden of an mostly-empty rack and signals investment overkill for a hobby that may not sustain that level of commitment. PROSCALE’s modular design solves this by starting small (a single 60-slot rack) and expanding horizontally or vertically as the collection grows.

HYBRID COLLECTIONS AND MULTI-BRAND COMPATIBILITY
Many Vallejo painters eventually add paints from other brands — typically Citadel or Army Painter — either by accident (gift sets containing mixed brands) or by design (testing a competitor’s formulation). This creates a storage problem: Citadel pots are 32mm wide, requiring 33mm slots; Army Painter and Vallejo are both 26mm. A mixed collection forces a choice.
The first option is parallel racks. Keep Vallejo and Citadel separated into different 26mm and 33mm racks, respectively. This is the cleanest solution if the Citadel portion of the collection is substantial (30+ bottles). Separate racks also prevent confusion during painting sessions — no risk of accidentally grabbing a Citadel pot when reaching for a Vallejo dropper.
The second option is a single mixed-slot rack. PROSCALE offers configurations with adjustable slot diameters or dedicated sections for different widths. A painter can run 26mm slots for Vallejo and 33mm slots for Citadel in the same modular system. Visually, this works best if the larger Citadel section is at the bottom (ground-level visual hierarchy) and Vallejo droppers fill the upper sections.
The third option is a color-family organization that transcends brands. Group all reds together regardless of brand, all blues together, regardless of whether they’re Vallejo Model Color or Citadel Base. This requires either a mixed-slot rack or careful height management to make bottles from different widths visible. This approach is effective only if the Citadel or other-brand portion is small (fewer than 20 bottles) and the painter’s workflow prioritizes color matching over batch consistency.
For painters with small mixed collections, the simplest solution is to select the primary brand’s slot size and accept that the secondary-brand bottles may sit lower or higher than ideal. A painter with 100 Vallejo bottles and 15 Army Painter washes can fit all 115 in a 120-slot 26mm rack, with the Army Painter bottles indistinguishable in their slots. The bottles are visible, accessible, and the rack remains functional.

OPERATIONAL SCENARIO
A painter named Sarah received a Citadel paint set as a gift and had already invested in 90 Vallejo Game Color and Model Color bottles. She purchased a standard 26mm modular rack designed specifically for Vallejo compatibility and filled it with careful organization by color family. When she opened the Citadel set, she attempted to fit the wider 32mm pots into the same rack. The first one fit, barely, but pushed adjacent Vallejo droppers inward, making them partially hidden. By the fifth Citadel pot, she realized the whole system was compromised — her carefully organized color family sections were disrupted, and visibility was worsening.
Sarah made the decision to purchase a second, smaller 33mm-slot rack specifically for the Citadel pots. She kept the original Vallejo rack unchanged. Within weeks, she began preferring the Citadel paints for certain projects and added to that collection. Separating the brands meant she could optimize each collection independently — the Vallejo section remained organized by color family, and the Citadel section organized by paint type (Base, Layer, Shade). The lesson: mixed-width collections benefit from separation, not compromise. If a secondary brand reaches 20+ bottles, it deserves its own rack.
FAQ
What size are Vallejo paint bottles? Vallejo dropper bottles are 17ml with a 26mm diameter — the industry standard for modular paint racks. Vallejo’s 72ml airbrush bottles are 39mm in diameter and require wider slots or separate storage. The dropper format fits any PROSCALE 26mm-slot rack without modification.
Do Vallejo bottles fit in a standard paint rack? Standard 26mm paint racks accommodate Vallejo dropper bottles perfectly. Vallejo itself engineered the dropper format to the 26mm standard, so compatibility is guaranteed. If the rack is labeled “26mm” or “Vallejo-compatible,” the fit is secure and snug without play.
How many Vallejo bottles can fit in a single rack? A typical 26mm modular rack holds 60 to 120 bottles depending on configuration. Most painters use 60-slot or 80-slot racks for Vallejo collections up to 100 bottles. A painter with 150+ Vallejo bottles typically uses two racks or one large wall system, but the choice depends on workspace constraints.
Can you store 72ml Vallejo airbrush bottles with dropper bottles? Technically yes, but not recommended. The 72ml bottles are 39mm in diameter — too wide for 26mm slots and too heavy to mix with narrow droppers without crushing them or obscuring them. Separate the airbrush bottles into a dedicated 35mm+ slot rack or store them horizontally on a shelf.
Should I organize Vallejo paints by color or by range? Both systems work, depending on painting workflow. If you paint by project and switch mediums frequently, organize by range (Game Color separate from Model Color). If you paint by color-matching speed and rarely switch ranges, organize by color family. Most painters switch between both methods seasonally or by project.
How do I store Vallejo Metal Color and Liquid Metal together? Store them in a separate dedicated section of your main rack or in a secondary 26mm-slot rack. While the bottles are 26mm compatible, the paint chemistry is different — lacquer-based in Liquid Metal’s case — and accidental mixing with acrylics can occur if stored in close proximity. Keeping them visually distinct prevents workflow errors.
If your Vallejo collection spans multiple ranges and bottle types, a modular system designed for 26mm droppers with expandable options for larger airbrush bottles grows with your hobby. → View the full PROSCALE range →
