🛋️ Throw Pillow Arrangement Planner
Choose your sofa, sectional, or bed and get a recommended pillow count, sizes, and a concrete layout — built on the pairs-plus-a-lumbar rules interior designers actually use.
🧮 Plan Your Pillows
🛋️ Recommended arrangement
| Corner pair | 2 × 22" square |
| Inner pair | 2 × 20" square |
| Center lumbar | 1 × 12×20" lumbar |
| Total pillows | 5 |
On a standard sofa, place a 22" square in each corner, a 20" square just inside each, and a 12×20" lumbar in the center — a classic symmetric five.
Stop guessing how many pillows to buy
Too few pillows and a sofa looks bare; too many and there's nowhere to sit. The designer answer is a simple recipe — work in pairs, mix two or three sizes, and anchor the middle with a lumbar. This planner applies those rules to your exact furniture and hands you a shopping list.
Use the suggested sizes as a guide and adjust to taste: a slightly larger corner pillow always reads as more luxurious, and a single off-center accent keeps the look from feeling stiff.
❓ Frequently Asked Questions
How many throw pillows should a sofa have?
A standard 3-seat sofa looks best with five: a pair of larger 22-inch squares in the corners, a pair of 20-inch squares just inside, and a lumbar in the center. A compact sofa or loveseat carries three — a pair plus a lumbar. Large sofas and sectionals can take six or seven if you break the symmetry with an accent size.
What's the difference between symmetric and asymmetric?
Symmetric means matched pairs mirrored on each side — calm, tidy, and a little formal. Asymmetric mixes sizes and offsets the lumbar to one side for a relaxed, collected-over-time look. This planner suggests symmetric layouts for sofas and beds, and an asymmetric cluster for sectionals, but either rule works if you keep to two or three sizes.
How should I layer pillows on a bed?
Work front to back: stand euro shams (26-inch squares) upright against the headboard, layer standard or sleeping shams (20-inch) in front, then finish with a single lumbar or bolster at the front. The number of euros scales with the bed — one for a twin, two for a full or queen, three across a king.
Do all my pillows need to match?
No — matching everything looks flat. The reliable formula is to vary size and texture while keeping a shared color thread: pick one patterned pillow, one solid, and one with texture within the same palette. Odd numbers and a mix of sizes almost always look more designed than a row of identical squares.
