The Atelier
Eight tools
that measure
instead of guess.
Hanging height, gallery walls, frames and mats, light, palette, scale, your collector type and the value of an edition. Each one is a small instrument, not a quiz with a shop at the end.

01The 150 line
Hanging Height
Height of the work, the furniture under it, the hardware on the back. Out comes the hook height in centimetres and where the second hook goes.

02Paper first, on screen
Gallery Wall
Your wall, your furniture, your frames, drawn to scale. Drag them into a composition, snap the gaps, print the layout with hook heights.

03Sizes and glass
Frame and Mat
Sheet size in, everything else out: mat borders with the weighted bottom, outer frame size, glass area, weight and a cost band by glazing.

04Thirty degrees
Art Light
Ceiling height, centre of the work, what it is made of. Out comes the distance of the spot from the wall, the beam angle, the lux limit and how many years you have.

05Colour from the canvas
Palette from a Work
Load a photograph of the work. The tool reads its five main colours in order of area and turns them into a wall, two textiles and one accent, with the hex codes.

06Two thirds
Scale Finder
Sofa width, wall width, ceiling. Out comes the right size for one work, a pair or a triptych, drawn to scale above your furniture.

07Eight questions
Collector Type
Not what you like. How you live with it: walls, patience, budget, the urge to rearrange. One of six collector types comes back, with three works from the Show and the tools that fit.

Edition Guide
Print type, edition size, signature, the stage of the artist, condition and where it came from. The tool turns them into a share of what a unique work by the same artist costs.

Rules of thumb, stated as rules.
The values behind these tools are the ones museum registrars, framers and lighting designers actually use: 145 to 155 centimetres for the centre line, 50 lux for paper, 30 degrees for a spot, two thirds of the furniture for the width. They are starting points that work in almost every room, and the tool tells you when yours is the exception.
