A specification sheet (spec sheet) is a document that records the exact details of a product or material chosen for a project, so it can be priced, ordered and installed without ambiguity.
What it usually contains
- Item code and the room or location it is for.
- Manufacturer, product name and model number.
- Dimensions and quantity.
- Finish, color and material (with fabric or paint codes).
- Supplier, price and lead time.
- Installation notes, care instructions and certifications (fire rating, for example, in commercial work).
- An image or drawing of the item.
Why it matters
“A green velvet sofa” can mean hundreds of products. A spec sheet removes the guesswork, protects the design intent when contractors or buyers change, and is the basis of the FF&E schedule.
AI images are not specifications: an AI-rendered chair may not exist. Once you like a redesign, find real products, for example with Tigmi’s Shop the Look, and record them properly.
