Quick Answers
- What is the most important single piece of information to give a wall art supplier? The finished size of each piece, including whether the measurement includes the frame. Without this, every other specification is approximate.
- How precise does my size specification need to be? Within ±2 cm is workable for most formats. Canvas and giclée can often be produced at any custom size; some metal formats have standard increments.
- Can I specify a Pantone or RAL colour reference instead of a description? Yes. This is the most reliable way to communicate a colour requirement — Pantone Textile, Pantone Coated, or RAL Classic are all workable. Verbal descriptions like “warm beige” vary between monitors, print proofs, and observers.
- What compliance documentation should I request upfront? For projects with California compliance requirements, ask for CARB Phase 2 documentation for any MDF or composite wood components. For wider material compliance, Bureau Veritas material test reports cover canvas surface coatings.
- What is a realistic lead time for a 100-piece hotel project? Giclée canvas: 15–25 working days FOB. Hand-painted oil: 20–35 working days. Metal formats: 20–30 working days. LED metal: 25–35 working days. These are from production start, not from inquiry date — allow 3–7 working days for sample confirmation before production start.
Getting a precise, actionable quotation from a wall art manufacturer depends almost entirely on the quality of the brief you send. Vague specifications produce vague quotes — with line items for “contingencies” that rarely favour the buyer.
This guide covers the six specification dimensions that matter most for hotel, commercial, and hospitality art projects. Each one directly affects the quotation, the production timeline, and the quality of the finished piece.
1. Size: The Most Commonly Under-Specified Dimension
Most procurement briefs specify a target size. Fewer specify whether that size includes the frame, what tolerance is acceptable, and what happens if the standard size is 5 cm off from the wall space available.
What to specify:
- Finished dimensions (H × W), stated as including or excluding frame
- Acceptable tolerance: ±2 cm is standard for canvas formats; metal formats may have tighter or looser increments depending on the substrate
- Whether the measurement is to fit a specific recess or wall section — suppliers need to know if this is a constraint or a guide
- Whether pieces in the same zone need to match exactly (e.g., four identical guest-room pieces, same dimensions across all 120 rooms)
For large-format hotel lobby pieces, sizes above 120 × 160 cm are available in giclée and oil formats. Metal and LED formats may have practical upper limits depending on substrate gauge.
Colour match across rooms matters more than size precision for most FF&E projects. A ±3 cm size deviation is invisible in a finished room. A ΔE 3.5 colour deviation between two pieces on the same wall is not.
2. Substrate: What the Art Is Printed or Painted On
The substrate is the surface that carries the image or paint. For commercial projects, substrate choice affects durability, weight, cleaning protocols, and compliance.
Common substrates for commercial wall art:
| Format | Substrate | Weight per m² | Wipe-clean |
|---|---|---|---|
| Giclée canvas | 300–380 gsm cotton or cotton-blend canvas | Light | Dry wipe only |
| Crystal porcelain | Rigid ceramic-composite panel | Heavy | Wet wipe safe |
| Crystal film | High-gloss laminate on rigid backing | Medium | Wet wipe safe |
| Handcrafted oil | Linen or cotton canvas | Medium | Dry wipe only |
| Powder-coated metal | Steel or aluminium panel | Heavy | Wet wipe safe |
| Glass micro-engraving | High-clarity glass panel | Heavy | Glass cleaner safe |
Specify the substrate when:
- The project is in a high-humidity environment (coastal resorts, spa areas, bathrooms adjacent)
- Cleaning protocols require wet-wipe or disinfectant-wipe compliance
- The project requires clinical-grade surface finishes (healthcare, aged care)
- Pieces will be installed in high-traffic corridors where surface contact is likely
For projects in California or states with CARB Phase 2 requirements, specify that MDF or composite wood components must comply with TSCA Title VI limits. SGS testing of our MDF frame components has returned 0.08 ppm — below the 0.11 ppm Phase 2 limit for standard MDF.
3. Frame and Finishing: Alignment with Interior Palette
Frame selection is often left to the supplier’s standard options — which works for straightforward projects but creates problems when a design scheme specifies a particular metal finish, wood tone, or profile width.
What to specify:
- Frame material: aluminium alloy / solid wood / MDF with veneer / no frame (gallery-wrap)
- Finish: powder-coated colour (specify RAL or Pantone if critical) / brushed / polished / natural wood stain
- Profile width: narrow (15–20 mm) / standard (25–35 mm) / wide decorative (50 mm+)
- Corner treatment: square-cut / mitre join / decorative moulding
- D-ring position or hanging system, if you have a specific fixing requirement
For hotel projects where 100+ pieces share the same frame specification, consistency of finish across the batch matters. Powder-coated finishes on aluminium are more consistent than painted wood finishes across large volumes.
4. Lead Time: Building a Realistic Installation Schedule
Lead time begins from production start, not from the date of inquiry. Build in time for the following steps before production begins:
| Step | Typical duration |
|---|---|
| Quotation and confirmation | 3–5 working days |
| Sample production | 7–12 working days |
| Sample review and approval | 3–7 working days (client-side) |
| Total before production start | 13–24 working days |
Then add production lead time by format:
| Format | Production lead time (FOB Xiamen) |
|---|---|
| Giclée canvas | 15–25 working days |
| Hand-painted oil | 20–35 working days |
| Metal formats | 20–30 working days |
| LED metal art | 25–35 working days |
| Crystal porcelain | 20–28 working days |
Sea freight from Xiamen to Los Angeles: 15–20 working days. Xiamen to Dubai: 18–22 working days. These are transit times after the shipment leaves the factory.
For hotel opening deadlines, work backwards from installation week. Add buffer for customs clearance (typically 5–10 working days) and on-site installation (varies by project scope).
A 100-piece giclée project with sample approval, FOB to the US West Coast, and customs clearance requires a minimum of 11–13 weeks from first inquiry to pieces on the wall. Projects with faster timelines exist but require pre-approved specifications and reduced sample review cycles.
5. Compliance Documentation: What to Request and When
Compliance documentation is most valuable when you request it as part of the quotation process, not after the order is placed. Not all suppliers hold the same certifications, and the documentation available varies by product type.
What to request, and what it covers:
| Document | What it covers | When to request |
|---|---|---|
| SGS CARB Phase 2 (MDF components) | Formaldehyde emissions from composite wood; 0.08 ppm tested result | California projects, US domestic compliance |
| Bureau Veritas material test report (canvas) | Total lead, cadmium, phthalate content of canvas surface materials | Wide regulatory compliance, European projects |
| CO (Certificate of Origin) | Country of manufacture | Required for customs declarations |
| Fumigation certificate | Wood packaging compliance (ISPM 15) | Required for most import markets |
| Material Safety Data Sheet (MSDS) | Chemical composition of inks and coatings | Required for some institutional purchasing |
What is not available as a standard document:
- Completed products tested as whole assemblies (most compliance testing is per-material, not per-finished-product)
- Certifications for LED components and electronics (typically CE and UL certified at the component level by the component manufacturer, not by the art manufacturer)
Request documentation requirements in your RFQ. Suppliers who cannot provide relevant documentation upfront are unlikely to produce it after an order is placed.
6. Typical Application: Matching the Format to the Space
The final dimension to specify is the most often overlooked: where the piece is going, and what it needs to do there.
Different commercial spaces create different requirements:
| Application | Key considerations | Format recommendation |
|---|---|---|
| Hotel guest rooms (standard) | Mid-range viewing distance (2–3 m), high piece count, colour consistency | Giclée canvas — consistent across batches |
| Hotel lobby / feature wall | Long viewing distance (5–10 m), statement scale | Large-format oil or metal; LED for lighting ambience |
| F&B / restaurant | Proximity viewing, moisture exposure possible | Crystal film or porcelain; avoid uncoated canvas |
| Corporate boardroom | Formal tone, precision colour | Giclée or limited-edition oil; custom framing important |
| Healthcare / aged care | Wipe-clean surface, anti-ligature fixings, calming subject | Crystal porcelain or metal; radius corner frames |
| GCC hospitality / Islamic spaces | Islamic calligraphy content, material appropriate to cultural context | Glass micro-engraving or mirror etching |
| Coastal resort | Humidity resistance, subject alignment | Metal or crystal porcelain; marine or nature subjects |
Include this in your specification: a one-line description of the space, the expected occupant type, and any environmental factors (humidity, direct light exposure, cleaning protocol). Suppliers can then flag format risks before sampling rather than after production.
How to Structure Your Specification Brief
A usable brief for a custom wall art project covers these six dimensions in writing, with enough precision to produce an accurate first-round quotation:
1. Size: [H] × [W] cm, including / excluding frame
2. Substrate: canvas / metal / porcelain / glass (wipe-clean: yes / no)
3. Frame: material / finish / profile / no frame
4. Lead time: required installation date / flexibility
5. Compliance: CARB Phase 2 required / BV documentation required / other
6. Application: [space type / occupant / any environmental notes]
Adding a floor plan with indicated wall positions, or a reference image for colour direction, reduces back-and-forth at the RFQ stage and typically shortens the timeline to a firm quotation.
FAQ
Q1: Can I supply my own image files for a custom giclée print?
Yes, for giclée and canvas prints, client-supplied artwork files are standard. Minimum file resolution is 150 DPI at finished print size for viewing distances over 2 m; 300 DPI is required for close-range viewing (under 1.5 m). Accepted formats: TIFF, PSD, PDF (print-ready). For pieces going to California, confirm CARB Phase 2 compliance of any MDF components before production.
Q2: How many sample rounds should I budget for?
Standard practice is one sample round (first article approval), with a second round if revisions are required. For large projects (50+ pieces), a second-round sample is common after production begins to confirm colour consistency before full-batch completion. Build 7–14 working days per sample round into your schedule.
Q3: What is the minimum order for a custom colour or size?
For giclée canvas with a custom size: no minimum order — single pieces can be produced. For hand-painted oil with a custom subject: minimum typically 1 piece, though unit cost decreases with volume. For metal formats with a custom powder-coat colour: standard minimum is 5 pieces (a single custom colour match requires calibration that is economical across a small batch). Project quotation provided on request.
Q4: Does specifying a Pantone reference guarantee the print will match?
A Pantone reference enables a specific colour target during print calibration, but it does not guarantee a perceptual match across all substrates and viewing conditions. Canvas absorbs inks differently from coated paper; some Pantone colours contain fluorescent components that cannot be reproduced in archival pigment inks. Buyers should request a printed proof at approved specifications — the approved proof, not the Pantone swatch, becomes the production reference.
Q5: What happens if pieces arrive with visible colour variation across the batch?
Batch Delta-E tolerance is ≤1.5 as a standard production target. Variation above ΔE 2.0 is visible to most observers under consistent lighting and warrants a production review. Pre-shipment photography is standard before dispatch — visual confirmation of colour consistency across the batch is provided for approval before shipment. For projects requiring formal Delta-E batch documentation, third-party colour measurement can be coordinated on request (adds 2–3 working days).
Q6: Are there frame options that comply with anti-ligature requirements for healthcare?
Yes. Radius-corner frame profiles and tamper-resistant fixings are available for healthcare and aged-care installations. Frame components meet standard clinical environment specifications; anti-ligature compliance testing per specific institutional requirements should be confirmed with your facilities management team and documented in the project specification.
