Planning a brick mosaic — baseplates, pieces and parts lists

Brick mosaics turn photos and designs into wall art made of tiny square or round pieces on a baseplate. Good planning, especially around colours and part counts, is the difference between a satisfying build and a pile of the wrong pieces.

Key takeaways

  • One stud, one 1 × 1 piece: a 32 × 32 baseplate (about 25.6 cm) takes 1,024 pieces.
  • Mosaics are low resolution, so bold, simple pictures work best; faces usually need 48–64 studs across.
  • Check the parts list and merge colours that are hard to buy in 1 × 1 pieces.
  • Add 2–5% spares of each colour for pieces that go astray.
  • Heavier chart lines every 16 studs; every second one marks a plate edge.

How brick mosaics work

A brick mosaic is a grid of 1 × 1 pieces pressed onto a baseplate, one piece per stud. Each square of the chart is one piece. The standard large baseplate is 32 × 32 studs, about 25.6 cm across, and larger pictures use several baseplates side by side.

PlatesStudsFinished size
132 × 3225.6 × 25.6 cm (10 in)
2 × 164 × 3251 × 25.6 cm
2 × 264 × 6451 × 51 cm (20 in)
3 × 396 × 9677 × 77 cm (30 in)

Every stud needs a piece, so a single 32 × 32 plate takes 1,024 pieces and a 2 × 2 picture takes 4,096.

Choosing a picture

Mosaics are low resolution: a portrait across one plate is only 32 pieces wide. Simple, bold images work best:

  • A face or pet portrait, cropped tight.
  • Logos you own, symbols, letters and initials.
  • Landscapes with simple bands, such as sunsets, seas and mountains.
  • Pixel art and icons, which already fit a grid.

Test a few sizes in the brick mosaic pattern maker: faces often only become recognisable at 48 or 64 studs across. Here is how resolution grows with size, using our test photo:

Colours and parts lists

The biggest practical limit is which colours you can actually buy in 1 × 1 pieces. Choose a modest palette, then:

  1. Generate the chart and look at the parts list: it counts the pieces needed in each colour.
  2. Merge rarely used colours into a neighbour if that colour is hard to find.
  3. Add a few spares of each colour, about 2 to 5%, for pieces that ping across the room.
  4. Order or sort your pieces into labelled trays before building.

The background colour usually dominates the count. If it is a colour you cannot buy in bulk, it is often easier to change the background than to hunt for hundreds of one shade.

Building

  1. Sort first. Pour each colour into its own tray or bowl.
  2. Build row by row, checking each row against the chart; if you follow the written rows, they count from the bottom row up. The heavier chart lines every 16 studs help you keep your place, and on multi-plate designs every second heavy line marks a plate edge.
  3. Press each piece firmly so it sits flat; a brayer or a flat block pressed across a finished area seats everything evenly.
  4. Check as you go. It is much easier to fix a misplaced piece in the current row than once it is surrounded.

For multi-plate builds, finish each plate separately, then join them with connector plates on the back or mount them on a board.

Displaying it

Frame the plates in a deep frame, glue them to a painted board, or hang them with picture hooks on the back. Tile mosaics wipe clean with a dry microfibre cloth. The brick mosaic pattern library has one-plate designs to start with.

Frequently asked questions

How big is a 32 × 32 baseplate?

About 25.6 cm (10 inches) square. Studs are 8 mm apart, so 32 studs measure 256 mm.

Plates, tiles or round pieces?

Flat tiles give a smooth, modern surface; studded plates look more like classic bricks; round pieces give a pixel-dot look. They all fit one per stud, so the chart is the same.

How many colours should a mosaic use?

For a graphic design, 6 to 12. For a portrait, 10 to 20 shades of greys and browns works well. Fewer colours mean simpler ordering and a bolder look.

Are these official brand colours?

Our charts use generic colour names chosen to match commonly available solid colours. Check what is available from your supplier before you order.
