How Much Does 2.5L of Paint Cover?
Last reviewed: 9 September 2026
A 2.5L tin of standard wall emulsion covers around 35 m² with one coat, or roughly 17.5 m² once you've done two coats. That's based on Dulux's published coverage rate of up to 14 m² per litre for Matt and Silk emulsion. Other paint types cover a bit more per litre, so exact figures depend on what you're painting with.
2.5L coverage by paint type
2.5L is the smallest tin size Dulux sells for wall emulsion, and it's also available for woodwork and masonry paint. Coverage varies by product:
| Product | Published coverage | 2.5L, 1 coat | 2.5L, 2 coats |
|---|---|---|---|
| Dulux Matt (walls & ceilings) | Up to 14 m²/L | ~35 m² | ~17.5 m² |
| Dulux Silk (walls & ceilings) | Up to 14 m²/L | ~35 m² | ~17.5 m² |
| Dulux Weathershield Smooth Masonry | Up to 15 m²/L | ~37.5 m² | ~18.75 m² |
| Dulux Quick Dry Satinwood | Up to 16 m²/L | ~40 m² | ~20 m² |
| Dulux Quick Dry Gloss | Up to 16 m²/L | ~40 m² | ~20 m² |
Coverage figures from Dulux's published technical data sheets, checked August 2026. Rougher or more porous surfaces reduce real-world coverage by 10-20%.
How far 2.5L actually goes on a wall
Picture a single wall roughly 3.5m wide and 2.4m high - about 8.4 m². A 2.5L tin of emulsion, at two coats, covers that wall about twice over. For a full room, most people need a 5L tin rather than 2.5L. See our 5L coverage guide for the room-sized tin, or how much paint you need for a room for a full room-by-room breakdown.

How many square metres does a 2.5L tin of paint cover?
For Dulux Matt or Silk wall emulsion, a 2.5L tin covers around 35 m² with one coat or 17.5 m² with the recommended two coats, based on Dulux's published rate of up to 14 m² per litre.
Is 2.5L enough for one wall or a whole room?
2.5L, with two coats, is usually enough for one or two average walls (around 15-18 m² of wall area). For a full standard UK room (around 30-35 m² of wall area), you'll normally need a 5L tin. Use the calculator for an exact figure based on your room's dimensions.
Does 2.5L cover the same area for every paint type?
No. Matt and Silk emulsion cover up to 14 m²/L, masonry paint covers up to 15 m²/L, and satinwood or gloss covers up to 16 m²/L. A 2.5L tin therefore covers anywhere from 35 to 40 m² with one coat depending on which product you're using.
