Tamiya Paint Storage: Organizing Enamel, Acrylic, and Lacquer Collections
Tamiya 10ml jars and 23ml pots are shorter and wider than dropper bottles—most racks designed for Vallejo or Citadel won’t fit them without wider slots or adjustable configurations. Complete guide to Tamiya paint formats, rack compatibility, and organization by paint type.
Enamel paint: a solvent-based paint formulation that dries through solvent evaporation, not water. Tamiya enamels are renowned for high pigment density and finish quality in scale modeling, and they require separate storage from water-based acrylics to prevent accidental cross-contamination during application.
Paint jar: a cylindrical plastic container with a flip-top lid, wider and shorter than dropper bottles. Tamiya’s 10ml and 23ml jars are designed for brush loading rather than precision dispensing, and their proportions create a primary storage challenge in modular rack systems.
TAMIYA BOTTLE FORMATS AND SLOT SIZING
Tamiya manufactures paint in two primary container sizes—10ml jars and 23ml pots—both wider and shorter than the dropper bottles that dominate the miniature painting market. This fundamental shape difference is the core storage challenge for Tamiya painters.
The 10ml jar is Tamiya’s standard format for color paints. It has a flip-top cap designed for brush loading—you dip your brush directly into the pot without a dropper or dispenser. The jar is approximately 28mm wide at the broadest point and stands roughly 20mm tall. The 23ml pot, used for Tamiya’s base coat and thinner ranges, is approximately 35mm wide and 25mm tall. These dimensions create a critical incompatibility with racks designed for 26mm dropper bottles like Vallejo or 33mm pots like Citadel. PROSCALE’s modular systems support wider-slot configurations specifically designed to accommodate Tamiya’s jar formats without visibility compromise.
A standard 26mm slot—the global format for Vallejo and Army Painter droppers—accommodates the Tamiya 10ml jar with limited clearance and significant height waste. The jar sits deeper in the slot than a dropper bottle would, partially hidden behind the lip of the rack. The visible label shrinks to a narrow strip at the top. Visual inventory becomes difficult. A 26mm rack designed for Vallejo droppers functions as a Tamiya storage solution, but it delivers poor visibility and ergonomic friction.
The 23ml pot is even more problematic in standard racks. At 35mm wide, it exceeds the 33mm Citadel slot standard and requires 40mm+ clearance. Storing 23ml pots in a 33mm slot is mechanically possible but creates dangerous tipping behavior—the pot rocks side to side, and gravity pulls it toward the front of the slot, creating an unstable, top-heavy presentation.

PAINT TYPE ORGANIZATION AND ENAMEL VS ACRYLIC SEPARATION
Tamiya produces four distinct paint chemistries, each requiring isolation from the others to prevent workflow errors and contamination.
Tamiya Acrylic paints are water-thinned acrylics in the 10ml jar format. These are Tamiya’s entry-level range for beginners and casual painters. They’re compatible with water cleanup and standard acrylic brushes. The palette is broad—100+ colors—but many painters view these as a starter or secondary range compared to the enamels for which Tamiya is known. In a storage system, Tamiya Acrylics occupy space proportional to a painter’s commitment to that range. A painter using them as a secondary option might own 20–30 jars; a painter focused on Tamiya Acrylic exclusively might reach 80+ jars.
Tamiya Enamel paints are the flagship product—solvent-based, high-pigment, and engineered for plastic model kits. They dry to a smooth, durable finish and remain the preferred choice for most scale modelers. Enamels come in the 10ml jar format and require solvent (mineral spirits, turpentine) for cleanup. A serious Tamiya modeler might own 80–150 enamel colors. The critical storage rule: enamels must be physically separated from acrylics. If a painter reaches into an acrylics section and accidentally grabs an enamel, the paint won’t behave on the brush or model—acrylics don’t thin with the same solvents, and enamels won’t adhere to acrylic base coats properly. Separation by color won’t work because both ranges use similar color names. Separation by physical location—different racks, different shelves, different walls—is essential.
Tamiya Clear and Semi-Gloss coats are specialized finishes for scale models. Clear coats are used to protect decals and create a uniform gloss or matte base before weathering. Semi-Gloss is an intermediate finish. These come in small volumes—a modeler might own 2–6 bottles. They should be stored near the enamels they’re used with, not with the acrylic range. In a PROSCALE system, a painter typically dedicates a small 5–10 slot section to finish coats, positioned adjacent to the main enamel storage.
Tamiya Lacquer is a specialty category. Lacquer-based paints are used for automotive and aircraft modeling where maximum durability and gloss finish is required. Lacquers are volatile—they require solvent cleanup, excellent ventilation, and careful storage away from heat. A painter using lacquers typically owns a small dedicated collection (10–20 colors maximum) and stores them apart from both acrylics and enamels. In fact, lacquers are often stored in a separate cabinet with additional ventilation, not on a standard wall rack.

SPRAY CAN STORAGE AND AIRBRUSH PREPARATION
Tamiya’s spray can range (TS, PS, AS series) represents a parallel storage problem distinct from jar storage. These cans cannot fit in any modular rack system—they’re too tall and cylindrical. Spray cans require a dedicated storage solution: vertical storage on a shelf, in a metal rack designed for aerosols, or in a spray can holder that clamps to a wall or workspace.
TS cans are Tamiya’s standard spray format—acrylic-based, water-thinned, designed for priming and basecoating. PS is lacquer-based. AS is adhesive spray. All three formats are roughly 8 inches tall and 2 inches in diameter. They cannot share storage with jars or pots. Most modelers solve this by dedicating a specific shelf to spray cans—a single horizontal tier above or below the jar storage where cans stand upright, labels facing forward.
Tamiya’s airbrush-ready paints are bottled in 23ml pots (the same size as the clear coat bottles). These are pre-thinned for airbrush use and come in limited colors—ten to twenty core colors per painter maximum. Storage strategy: place airbrush paints in the same general zone as other 23ml pots (near clear coats and glosses), not mixed with the 10ml enamel jars. This prevents accidentally loading a brush with airbrush paint when reaching for a jar color.

RACK COMPATIBILITY AND CUSTOM SOLUTIONS
No commercial rack is engineered specifically for Tamiya’s jar formats. PROSCALE offers modular options to accommodate wider jars, and several custom solutions exist for modelers committed to Tamiya storage.
The adjustable-slot rack is the closest fit. Some PROSCALE configurations feature slots with adjustable dividers—partitions that move horizontally to accommodate different widths. A painter can position dividers at 28mm spacing for 10ml jars and 40mm spacing for 23ml pots within the same modular frame. This solution works but requires manual adjustment and is less visually clean than fixed-width slots.
The mixed-slot rack is another option. A PROSCALE system can be built with some 26mm slots (for Vallejo or Army Painter if a painter mixes brands) and dedicated 35mm+ slots for the wider Tamiya jars. This requires custom assembly but is structurally sound and visually organized. The limitation: finding the exact configuration requires custom order—standard off-the-shelf options won’t include both 26mm and 40mm slots.
For painters unwilling to compromise on visibility, a custom solution is a dedicated wooden shelf with individual bottle holders—small cups or clamps that grip each jar by its lid, allowing jars to sit upright on the shelf with full label visibility. This is more labor-intensive to construct than purchasing a modular rack, but it offers maximum flexibility for odd-sized bottles.
The low-tech solution is horizontal storage on open shelving. 10ml jars can be stacked flat on a shelf two or three bottles high without tipping. This maximizes space but reduces visibility and makes inventory checks slower. Horizontal storage is practical for a painter with a small, stable Tamiya collection but less suitable for active painters frequently reaching for specific colors.

TAMIYA COLLECTION SIZE AND ORGANIZATION STRATEGIES
Tamiya painters follow a different growth arc than Vallejo painters, primarily because Tamiya’s audience is scale modelers, not miniature painters. Collections tend to build around specific projects—a WWII aircraft model, a 1970s race car, a contemporary tank—rather than broad hobby accumulation.
A beginner’s Tamiya starter set contains 12–24 basic colors in 10ml jars. These fit on a single small shelf or in a storage box. At this scale, dedicated rack storage is premature—a shallow drawer or cardboard organizer suffices.
A working scale modeler typically owns 40–80 enamel colors, accumulated over 2–3 years of building specific models. This collection benefits from dedicated shelf storage. If using wall-mounted organization, a single 40–60 slot rack with adjustable or wider slots accommodates this scale comfortably. At this level, organizing by paint type (separating enamels from acrylics) becomes logistically important—the painter has developed a reliable technique and knows which paint they’re reaching for.
A committed modeler reaches 80–150+ enamel colors, with smaller supporting collections of acrylics, clear coats, and specialty finishes. This requires two racks or one large wall system. Organization shifts to sub-organization within paint types: enamels organized by hue (reds together, blues together, earth tones together) or by model project. A painter with 120 enamels painting a diverse range of subjects—1/48 WWII aircraft, 1/35 modern vehicles, 1/72 helicopters—might organize by project to minimize cognitive load during focused modeling sessions. A painter specializing in a single subject (all aircraft, for example) might organize by color family to maximize spray efficiency.
Serious modelers often reach 150–250+ enamels plus significant acrylic and specialty collections. At this scale, a dedicated modeler’s room with multiple wall racks is the standard solution. Organization is hybrid: primary racks for working colors (the 50–80 enamels used frequently), secondary racks for specialty colors and projects, spray cans on a dedicated shelf, and clear coats in easy reach of the painting desk.
TAMIYA BOTTLE DIMENSIONS AND COMPATIBILITY REFERENCE
| Tamiya Range | Format | Volume | Diameter | Height | Required Slot Width | Notes |
|---|---|---|---|---|---|---|
| Acrylic | Jar | 10ml | 28mm | 20mm | 30mm+ | Water-based; separate from enamels |
| Enamel | Jar | 10ml | 28mm | 20mm | 30mm+ | Solvent-based; standard modeler choice |
| Clear Coat | Pot | 23ml | 35mm | 25mm | 40mm+ | Specialty finish; small volume |
| Lacquer | Bottle | varies | varies | varies | Custom | Volatile; requires separate storage |
| Spray (TS) | Aerosol | — | 50mm | 200mm | Shelf storage | Vertical only; no rack mounting |
| Spray (PS) | Aerosol | — | 50mm | 200mm | Shelf storage | Lacquer-based aerosol |
| Airbrush-Ready | Pot | 23ml | 35mm | 25mm | 40mm+ | Pre-thinned; separate from jar colors |
The critical takeaway: Tamiya jars require minimum 30mm slots for 10ml colors and 40mm+ slots for 23ml pots and coats. Standard Vallejo-compatible (26mm) and Citadel-compatible (33mm) racks are functional compromises, not optimized solutions.
HYBRID COLLECTIONS AND MIXING TAMIYA WITH OTHER BRANDS
Most serious scale modelers eventually add paints from other brands—Testors enamels, Revell Aqua, or even Vallejo Model Air for specialized techniques. Mixing different brands creates storage complications similar to mixing Vallejo and Citadel, but compounded by Tamiya’s unique jar format.
If a modeler adds Vallejo to a Tamiya-focused system, the solution is segregation. Vallejo droppers (26mm) cannot coexist with Tamiya jars (28mm/35mm) in the same slots without compromising visibility. The most practical approach is two separate racks: a 26mm-slot rack for Vallejo and a 30-40mm adjustable or wider-slot rack for Tamiya. This forces a slight workspace expansion but maintains clarity.
If a modeler mixes Tamiya enamels with Testors enamels (a common combination for scale modelers), both brands use similar jar formats and can occupy the same racks. Testors jars are approximately 27–28mm wide, compatible with Tamiya 10ml storage. If both brands are solvent-based enamels, they can be stored together without separation concerns. Organization is then by color family or by specific project.
If a modeler adds Revell Aqua Color (water-based acrylics) to a Tamiya enamel collection, strict physical separation is critical. Revell Aqua jars are approximately 25mm diameter—too small for standard modeler racks but potentially usable in a Vallejo-style 26mm slot system. A modeler with significant Revell Aqua would benefit from a dedicated 26mm-slot rack to keep acrylics away from enamels, even though the visual organization is not ideal.

OPERATIONAL SCENARIO
A model kit builder named Marcus invested heavily in Tamiya enamels over five years—he built WWI aircraft models exclusively and accumulated 130 Tamiya enamel colors organized loosely in a cardboard tool organizer on a shelf. He supplemented these with a few Vallejo Model Color droppers (approximately 15 bottles) for specialized dry-brushing and weathering. When Marcus decided to upgrade to a professional wall-mounted storage system, he purchased a standard 26mm dropper-bottle rack designed for Vallejo collections, believing it would work for his Tamiya jars as well.
When his racks arrived and he began loading them, Marcus encountered immediate problems. The Tamiya 10ml jars fit into the 26mm slots but sat so deep that only the rim of each jar was visible above the slot lip. Labels were almost entirely hidden. He could see approximately 50 jars instead of 130, making color selection difficult. After loading 40 jars, Marcus realized his approach was flawed.
He purchased a second, custom-built rack with 35–40mm adjustable slots specifically designed for wider jars. He moved all Tamiya enamels to the custom rack, organized by hue (reds, blues, earth tones), and dedicated the original 26mm rack exclusively to his 15 Vallejo droppers and other miscellaneous narrow bottles. Visibility improved dramatically. Inventory management became manageable. The lesson: Tamiya jars require dedicated storage. Using a dropper-bottle rack creates a false economy—the bottles fit, but visibility and ergonomics suffer. Investing in wider-slot racks proportional to the collection size yields better long-term organization.
FAQ
What size are Tamiya paint jars? Tamiya 10ml jars are approximately 28mm wide and 20mm tall. Tamiya 23ml pots are approximately 35mm wide and 25mm tall. Both are wider and shorter than standard dropper bottles (26mm Vallejo/Army Painter or 33mm Citadel). The wider format is optimized for brush loading, not dropper dispensing.
Can you use a Vallejo paint rack for Tamiya? Technically yes, but with significant visibility compromise. Tamiya 10ml jars fit into 26mm slots but sit too deep in the rack, hiding the labels. Only the rim of each jar is visible, making color selection difficult and slow. A rack with 30mm or adjustable slots is a better choice if you own primarily Tamiya paints.
How many Tamiya bottles fit in a rack? A standard 40–60 slot rack with 30–35mm slots accommodates 40–60 Tamiya 10ml jars. The exact number depends on slot spacing. If using a modular system with adjustable dividers, you can fit more bottles by tightening spacing, but visibility decreases. Most modelers prefer spacing that allows full label visibility, which typically yields 40–50 bottles per 60-slot frame.
Should I store Tamiya enamels and acrylics together? No. Tamiya enamels are solvent-based, and acrylics are water-based. Storing them in the same rack creates workflow confusion—you can accidentally grab an enamel when reaching for an acrylic, and the paint won’t behave correctly on the model. Separate them into different racks, different shelves, or clearly distinct sections if using a mixed system. The separation prevents accidental contamination during painting.
How do you organize Tamiya spray cans? Spray cans cannot fit in any modular rack system. They require vertical shelf storage on a dedicated tier, in a commercial aerosol can holder, or clipped to a wall-mounted organizer. Most modelers place spray cans on a shelf directly above or below their paint jar racks for ergonomic convenience.
Can Tamiya paints mix with Vallejo or Citadel? Vallejo droppers (26mm) and Tamiya jars (28–35mm) are incompatible in the same slots without visibility compromise. Citadel pots (32mm) are closer in width to Tamiya 10ml jars but still not optimal. If you own both, use separate racks designed for each format. Mixing in a single rack forces you to accept poor visibility for at least one brand.
If your Tamiya collection has outgrown shelf storage and you’re ready for organized wall-mounted access, a modular system with wider slot configurations accommodates the larger jar format while keeping colors visible and inventory clear. → View the full PROSCALE range →
