Voting Scales
Choose the right estimation scale for your team — Fibonacci, T-shirt, or custom.
Scale types
GiveItPoints supports two types of voting scales:
- Numeric scales — values like Fibonacci numbers that allow mathematical analysis (average, closest value).
- T-shirt scales — relative sizing labels (XS through XXL) that use mode-based statistics.
The scale type determines how results are calculated when a session is finalized.
Numeric presets
| Preset | Values |
|---|---|
| Standard Fibonacci | 1, 2, 3, 5, 8, 13, 21, 34, 55, 89 |
| Short Fibonacci | 1, 2, 3, 5, 8, 13, 21 |
| Powers of 2 | 1, 2, 4, 8, 16, 32, 64 |
T-shirt size mapping
| Label | Numeric Equivalent |
|---|---|
| XS | 1 |
| S | 2 |
| M | 3 |
| L | 5 |
| XL | 8 |
| XXL | 13 |
How scale type affects statistics
Numeric scales produce an average vote and the closest scale value to that average. This works well when you need a single numeric estimate for sprint planning.
T-shirt scales produce a mode (most common vote). Since T-shirt labels represent relative sizes rather than precise numbers, the mode better captures team consensus.
Custom scales
You can customize the voting scale for any team. The facilitator can change the scale from the team settings at any time, even between sessions.
