THE NUMBERS, EXPLAINED
How to use this calculator.
One horizontal row on an uninterrupted wall segment after exclusions. Works are centered as a group with preferred internal gaps.
Start with your inputs
Enter usable uninterrupted wall length (cm), artwork widths in hanging order (cm), preferred gap between artworks (cm), minimum end margin (cm). Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Usable uninterrupted wall length (cm) | 400 |
| Artwork widths in hanging order (cm) | 60,80,60 |
| Preferred gap between artworks (cm) | 20 |
| Minimum end margin (cm) | 30 |
A worked example
With the example inputs above, hanging group width (cm) is 240. Change the inputs to explore your own scenario.
| Result | Example answer |
|---|---|
| Hanging group width (cm) | 240 |
| Equal end margins (cm) | 80 |
| Artwork left-edge positions (cm) | 80, 160, 260 |
| Meets minimum end margins | Yes |
How this is calculated
Hanging group width (cm)
Add artwork widths and internal gaps.
Equal end margins (cm)
Center the complete group on the wall.
Artwork left-edge positions (cm)
Start at centered end margin and add prior widths and gaps.
Meets minimum end margins
Compare centered margins with entered minimum.
Symbols and units
- a
- Usable uninterrupted wall length (cm)
- b
- Artwork widths in hanging order (cm)
- c
- Preferred gap between artworks (cm)
- d
- Minimum end margin (cm)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions and limits
One horizontal row on an uninterrupted wall segment after exclusions. Works are centered as a group with preferred internal gaps.
Calculations use the values you enter. Blank or invalid inputs show an error instead of silently substituting zero. Results are displayed to useful precision; calculations retain the underlying numeric precision.
Questions about this tool
What does the result tell me?
Hanging group width (cm); Equal end margins (cm); Artwork left-edge positions (cm); Meets minimum end margins. The result applies to the method and inputs described above. Check the units and assumptions before using it in a decision.
Why might another calculator differ?
Differences in units, rounding, timing or model definitions can produce different answers. Compare the input definitions and the method, rather than only the final number. For this tool: One horizontal row on an uninterrupted wall segment after exclusions. Works are centered as a group with preferred internal gaps.
