How To Measure For Outdoor Cushions (and Replace the Old Ones)

One of the joys of warm, sunny days is getting to spend time on the patio, deck, or in the yard—and those days are even better when you’ve got brand-new patio cushions. When your old patio cushions start to show wear, damage, fading, and mildew, it’s time for an upgrade. Start by learning how to measure for outdoor cushions using a flexible tape measure, then replace them with the right size, shape, fabric, and style. Following these easy steps will help you select the best outdoor furniture cushions for your patio seating.

Step 1: How To Measure Your Outdoor Cushions or Furniture

Taking accurate measurements is the best way to find the right size cushion for your furniture. Cushions that fit properly are more likely to stay in place and provide better comfort while you read, eat, or lounge. Avoid cushions that slip, slide, or bunch up by measuring your existing cushions or furniture to find the best size. There are two ways to determine the correct size for new cushions: either measure your existing furniture or measure the cushions you’re replacing. 

Here's how to measure for outdoor cushions:

1. Gather your tools: You'll need a flexible tape measure and a pen, and paper. 

2. Measure the existing cushions you are replacing. If you don’t have any cushions, measure the physical bench, chair, or lounger where you will use your new cushions. Write down these measurements: 

  • Width: Measure the widest part of the seat from side to side (usually at the front). 
  • Depth: Measure the seat from front to back at its deepest point. 
  • Thickness: Measure the cushion's height from top to bottom at its thickest point. 
  • Seat back: For lounge-style cushions, repeat the width, height, and thickness measurements for the backrest portion of the cushion.

3. Note additional details. To find a comparable replacement, you may need specifics like: 

  • Ties or attachments: Check if the cushions have any ties or attachment points and note their location and length. 
  • Special features: Account for any cushion features (bolsters, headrests, or curved edges) and consider these while shopping for replacements. 
  • Seam type: If you wish to match the appearance of your existing cushions, note the type of seam they have. It can be helpful to take photos for comparison as you shop.

Measuring Tips To Ensure the Best

Use these strategies when measuring for replacement outdoor cushions: 

  • Always double-check your measurements before ordering. 
  • For a snug fit, avoid sizing up more than ½–1 inch unless recommended by the manufacturer. 
  • If you’re measuring an existing cushion, allow for any shrinkage that has occurred due to use and fill compression. 
  • If you’re ordering from the same manufacturer, check the specifications provided by the brand for a perfect fit.
