How To Make: Super Simple LEGO Heart

What you need
Adult supervision required, assorted lego bricks and plates in lots of colors, flat baseplate or firm table to build on, ruler or straight edge for symmetry if you want it, small slope and curved bricks for rounding if you have them

Step 1

Gather your assorted LEGO bricks and plates and bring them to your building spot.

Step 2

Choose a flat baseplate or clear area on a table to be your heart workspace.

Step 3

Sort the bricks by color into small piles so you can find colors quickly.

Step 4

Decide whether you want a flat 2D heart or a standing 3D heart to build.

Step 5

Place a vertical row of plates or a line of bricks to mark the center line of your heart.

Step 6

Build one side of the heart by placing bricks next to the center line from the top toward the bottom.

Step 7

Mirror the same brick pattern on the other side to make the heart symmetrical.

Step 8

Add a border or a pattern using contrasting color tiles or plates to make your design pop.

Step 9

If you want a 3D heart stack bricks up along the heart edge to raise the sides a few layers.

Step 10

Fill the inside of the raised edge with plates or bricks to create the heart's volume.

Step 11

Smooth and shape the top with slope and curved bricks and add small decorative studs if you like.

Step 12

Share your finished LEGO heart on DIY.org

Final steps

You're almost there! Complete all the steps, bring your creation to life, post it, and conquer the challenge!

Help!?

I don't have a flat baseplate or slope bricks—what can I use instead?

If you don't have a flat baseplate use a sturdy piece of cardboard or a tray as your heart workspace, and replace slope or curved bricks by stacking plates or small wedge pieces to shape the top.

My heart keeps coming out lopsided—what step am I likely messing up and how do I fix it?

If your heart is lopsided, recheck the vertical center line you placed in Step 5 and rebuild one side to exactly mirror the other, then add plates or extra bricks along the edges to stabilize any wobbly 3D layers.

How can I adapt this activity for different ages?

For toddlers use large plates and make a simple flat 2D heart with color-sorted bricks, for elementary kids try a 3D heart with stacked layers and filling the inside with plates, and for older kids add slope and curved bricks, intricate patterns, or small decorative studs for detail.

What are some ways to extend or personalize my LEGO heart project?

Enhance your design by adding a contrasting color border with tiles, creating a mosaic pattern inside the heart from your sorted piles, smoothing the top with slope bricks, attaching small decorative studs, and then share the finished heart on DIY.org.

Facts about LEGO building for kids

❤️ LEGO heart designs are perfect for learning symmetry—mirror one side to make the other match!

🎨 LEGO bricks come in over 60 official colors, giving you tons of options to create colorful heart patterns.

🧠 Playing with LEGO helps improve spatial reasoning and pattern skills—great for learning geometry while having fun.

🏭 The Lego Group has produced hundreds of billions of bricks since the 1940s, so there are plenty for building 3D hearts and mosaics.

🧩 There are 915,103,765 ways to combine six 2×4 LEGO bricks, so your heart arrangements can be super unique.

How do I build hearts with LEGO step by step?

Start by choosing a baseplate or flat platform and pick a color palette. For flat heart shapes, map a simple symmetrical pattern, place plates and tiles mirroring each side. For 3D hearts, stack bricks in narrowing layers and slope pieces to round edges, mirroring both halves. Use a brick separator for adjustments. Encourage trying patterns, combining transparent pieces, and mounting finished hearts on a display plate or stringing them as garlands.

What materials do I need to build colorful LEGO heart shapes?

Gather a mix of LEGO plates, bricks, tiles, and slopes in various colors plus 1x1 and 2x2 pieces for detail. Include a baseplate or small display platform, LEGO Duplo for younger kids, and a brick separator for tricky connections. Add small trays or bowls to sort colors, scissors only if making paper labels, and optional clear stands, adhesive putty, or ribbon for hanging. Keep instructions or pattern printouts handy.

What ages is building LEGO hearts suitable for?

This activity suits children ages 3 and up with supervision. For under-3s, use DUPLO and close adult supervision due to choking hazards. Ages 4–8 gain fine motor skill practice and simple symmetry lessons; ages 9–12 can tackle more complex 3D models, pattern design, and color theory. Adjust complexity: pre-made templates for younger kids and open-ended challenges (mirror builds, timed design) for older children.

What are the benefits of building LEGO heart models with my child?

Building LEGO hearts boosts fine motor skills, spatial reasoning, and early geometry through symmetry practice. It encourages color recognition, pattern planning, patience, and problem-solving as kids adapt designs. Sharing or displaying creations builds confidence and communication skills. The activity also fosters creativity and cooperative play when done with friends or family, and can be extended into storytelling, card-making, or gifts for loved ones.
