5/8 yd
Cut 8 strips 2½″ wide across the width of fabric for 272″ of double-fold binding. Metric: 0.6 m.

How it's worked out

  1. Perimeter: (60 + 70) × 2 = 260″.
  2. Add about 12″ to join the ends and turn the corners: 272″.
  3. Each strip across 42″–44″ fabric gives about 40″ usable, minus ~2½″ for each diagonal join → 37½″ per strip.
  4. 272 ÷ 37½ = 7.25 → 8 strips. 8 × 2½″ = 20″ → round up to 5/8 yd.

Binding by strip width

Strip widthStripsBuyMetricBias (continuous)
2″ 8 1/2 yd 0.5 m 25 3/8″ square (3/4 yd)
2 1/4″ 8 1/2 yd 0.5 m 27″ square (3/4 yd)

3″ 8 3/4 yd 0.7 m 31 5/8″ square (1 yd)

Bias binding is only needed for curved or scalloped edges; straight-grain strips are fine for square corners.
