Which Paint Size Should I Choose? (10ml vs 50ml vs 250ml vs 1L)

Picking the right size paint is a key part in the process of painting. Whether you’re painting a staircase, a full kitchen or your internal doors is important as it ensure you avoid waste and complete your project without running out of paint.
In this guide, we’ll break down when to use each paint size available in The One for Wood range and help you make the best choice for your project.
Our Paint Sizes at a Glance
| Size | Coverage (approx.) | Best for |
|---|---|---|
| 10ml | Test swatch | Sampling on small areas |
| 50ml | 0.5 sqm (1 coat) | Testing on full pieces or patch testing finish |
| 250ml | 2.5 sqm (1 coat) | Furniture, cabinet fronts, or small panelled sections |
| 1L | 10 sqm (1 coat) | Stairs, full wardrobes, wall panels, large furniture |
10ml – For Quick Swatches & Colour Testing
These are mini sample sachets designed to help you see a colour in your space.
- Ideal for trying 2–3 colours on your project
- Helps you judge colour in natural vs artificial light
- Lets you test paint before committing
50ml – For Testing Full Surfaces
This sample tin gives you enough paint to:
- Cover ~0.5 square metres (1 coat)
- A great option to see the colour on a bigger surface or multiple doors
It’s perfect if:
- You want to test how smooth the finish looks
- You’re unsure if you like the colour on a larger area
- You need a bit of extra paint for touch ups
🎯 250ml – For Small to Medium Wood Projects
This is the most versatile size for small jobs:
- Covers 2.5 sqm (1 coat) = approx. 1.25 sqm with 2 coats
- Enough for:
- 4–6 kitchen cabinet doors
- Stair risers or handrails
- A single interior door
- Half a wall of wood panelling
1L – For Larger Projects or Full Room Details
This is the go-to size for:
- Staircases
- Wall panelling across full walls or rooms
- Kitchens
- Interior doors + trim
Covers:
- 10 sqm (1 coat)
- 5 sqm (2 coats) ← recommended for most wood projects
If you're painting an entire room of wooden panels or multiple large items, you may need more than one 1L tin. But for most medium-large projects, one litre is enough.
How to Choose the Right Size
Start with These Questions:
-
Are you testing a colour or painting the final project?
- If testing, go with 10ml or 50ml
-
How large is the area you’re painting?
- Measure width × height in metres, and multiply for sqm
-
Will you do one or two coats?
- Two coats = half the coverage listed per tin
-
Is the wood raw, rough, or previously painted?
- These may absorb more paint—round up!
