Gobo Fixture Compatibility, Gobo Size and Artwork Guide
Rosco steel & glass custom gobos · AU & NZ
Gobo Size & Fixture Compatibility — Match Your Fixture (AU & NZ)
The practical chart to match any fixture to the right Rosco gobo. Find your spotlight, moving head or projector, read off the outside diameter and image area, then order a custom steel or glass gobo cut precisely to size. Built for lighting designers, theatres, venues, hire companies and installers across Australia & New Zealand.
Why size matters
The right size projects cleanly and fits safely
Fits your fixture
Every gobo holder and wheel has a set diameter. Match it exactly and the gobo seats correctly, focuses cleanly and won't rattle, jam or overheat in the gate.
Sharp, full-frame image
The max image area is the largest artwork that projects without clipping. Design to it and your logo or pattern fills the beam edge to edge, in focus.
Steel or glass
Steel for breakups and single-colour patterns; glass for logos, gradients, fine detail and full colour. We cut both to any diameter for almost any holder.
Steel vs glass
Which gobo material should you choose?
Both mount the same way and use the same size chart below — the difference is what they can reproduce. Pick the material to suit the artwork, then order it in the diameter your fixture needs.
Steel (metal) gobos
Laser-cut single-layer patterns — the workhorse for texture and shape.
- Breakups, foliage, windows, bar patterns
- Simple single-colour logos and text
- Toughest option, handles the most heat
- Most economical for pattern work
Glass gobos
Photographic detail and full colour, printed and fired onto glass.
- Multi-colour logos and brand marks
- Gradients, halftones and photographic images
- Fine detail steel can't hold together
- Black & white, 1–3 colour or full colour
How to use this chart
Four steps from fixture to finished gobo
- Find your fixture brand and model. Jump to the brand section below (ETC, Chauvet, Selecon, Martin, Robe, Showtec, Neo Framer and more) and locate your exact model.
- Note the outside diameter and image area. The outside diameter is the physical size of the gobo blank; the max image area is the largest artwork that projects cleanly.
- Choose steel or glass. Steel for simple breakups and patterns; glass for logos, gradients, fine detail and full-colour artwork.
- Order your Rosco custom gobo from CFATS. Order online below, or email your artwork and fixture details and we'll handle the rest.

Standard gobo sizes (lettered)
Many fixtures use "standard" letter sizes. Always confirm against your fixture manual, but these common sizes are a good starting point when specifying gobos.

|---|---|---|---|
| A Size | 100 mm | 75 mm | Larger profiles / many 1–2 kW fixtures, some Selecon & Robert Juliat |
| B Size | 86 mm | 64 mm | Common for ETC Source Four, many profile spots |
| D Size | 53.3 mm | 40 mm | Smaller projectors and scanners |
| E Size | 37.5 mm | 28 mm | Compact profile fixtures & smaller projectors |
| G Size | ≈ 66 mm | ≈ 45–48 mm | Some Clay Paky and specialty fixtures |
| J Size | 38.8 mm | 25 mm | Smaller projectors |
| M Size | 66 mm | 48 mm | Used in many compact profiles (e.g. some Showtec, ETC Jr) |

| V Size | 22.5 mm | ≈ 17–22 mm | Very small scanners / moving heads |
Gobo sizes by fixture make & model

Send artwork that projects sharply
To achieve the sharpest projection, vector artwork is best. If you only have a basic logo or an unusual file type, just send it through — we'll review it and advise the best way to proceed.
File formats
Preferred (vector): AI, EPS, PDF.
Also accepted: PSD, TIFF, PNG, JPG — high-resolution only, suitable for full-colour or photographic gobos.
Resolution & size
- Metal gobos: min 150 dpi, 700 × 700 px or larger
- Glass gobos: min 300 dpi for clean, sharp projection
- Vector files: no resolution limits — scale cleanly at any size
A quick tip
Higher-quality artwork always produces a sharper projection. Bold shapes and clean lines read best; very fine hairlines can drop out at small sizes, especially in steel.

Case study · Metz Cathedral, France — 800th anniversary
Custom glass gobos guide a spiritual journey through a cathedral
For the 800th anniversary of Metz Cathedral, lighting designers Quartiers Lumières and graphic studio Nouvelle Étiquette used Rosco Image Spots with custom glass gobos to project poetic text — in a bespoke medieval-inspired typeface — across the walls, floors and columns. Each projection was sized to sit precisely within the architecture and programmed to fade slowly in and out, inviting visitors to look up and notice a detail they'd otherwise miss. It's a clear demonstration of why image area matters: the artwork was cut to land exactly where it needed to.
"The Image Spot projectors, sized to suit the project and DMX controllable, project perfectly sized images to fit in with the architectural details and warm lighting."Lionel Bessières — Lighting Designer, Quartiers LumièresRead it on Rosco Spectrum →

Case study · Varberg, Sweden — "The Enchanted City" festival
Custom gobos turn building façades into a festival of light
For the Rys och Mys ("Thrill and Chill") festival, lighting designer Johan Röklander of TRS Consulting used Rosco Image Spot HO projectors to throw stars, spiderwebs, hearts and children's own artwork across the façades of Varberg's buildings and fortress. Custom glass gobos carried the artwork; the higher-output fixtures let the team project from greater distances and onto more difficult, textured brick surfaces while keeping the colour saturated and the images crisp.
"The extra strength of the light allows us to project deeper colors on more difficult surfaces… the colors would not have been so clear."Johan Röklander — Lighting Designer, TRS ConsultingRead it on Rosco Spectrum →

Gobo FAQs
Sizing & ordering questions
How do I find the right gobo size for my fixture?
Find your fixture in the tables above and read off the outside diameter (the physical blank size) and the max image area (the largest artwork that projects cleanly). If your model isn't listed, send us the make and model — or a photo of the gobo holder — and we'll confirm the size.
Steel or glass — which should I order?
Use steel for breakups, textures, patterns and simple single-colour logos. Use glass for multi-colour logos, gradients, photographic detail and fine artwork that steel can't hold together. Both come in the same range of sizes.
My exact fixture isn't in the chart. Can you still help?
Yes. This guide covers the most common fixtures in Australia & New Zealand, but CFATS can manufacture a Rosco custom gobo to almost any diameter, in steel or glass, for nearly any holder or wheel. Just tell us the make and model, or send a photo of the holder or an existing gobo.
What artwork should I supply?
Vector files (AI, EPS, PDF) are best and scale cleanly. We also accept high-resolution PSD, TIFF, PNG or JPG for full-colour or photographic glass gobos — 300 dpi for glass, 150 dpi (700 × 700 px or larger) for metal.
Do you deliver across Australia and New Zealand?
Yes. CFATS is the exclusive Rosco agent for Australia & New Zealand and supplies custom gobos to theatres, venues, hire companies, AV integrators and installers throughout both countries.
