A5 vs 5R
A5 is 21 mm wider and 32.2 mm taller than 5R. They are close but not interchangeable: a layout built for one clips or leaves a border on the other.
Compare a Different Pair
A5 and 5R, Side by Side
| A5 | 5R | Difference | |
|---|---|---|---|
| Millimetres | 148 × 210 | 127 × 177.8 | 21 × 32.2 mm |
| Inches | 5.83 × 8.27 | 5 × 7 | 0.83 × 1.27 in |
| Centimetres | 14.8 × 21.0 | 12.7 × 17.8 | |
| Area | 0.0311 m², 31,080 mm² | 0.0226 m², 22,581 mm² | 1.38× |
| Aspect ratio | 1 : 1.419 (√2) | 1 : 1.400 | same |
What Is Lost Printing One on the Other
At 100% scale, both centred, nothing resized. A positive figure on the wider or taller side is cropped; on the other it is a blank margin.
| Axis | Gap | A5 onto 5R | 5R onto A5 |
|---|---|---|---|
| Width | 10.5 mm (0.41 in) each side | A5 loses it | blank band |
| Height | 16.1 mm (0.63 in) each end | A5 loses it | blank band |
Scale-to-Fit Percentages
The figure to type into a printer or PDF dialog to scale one to fit inside the other:
| 5R to fit A5 | 117% | leaves a thin border on one pair of edges |
|---|---|---|
| A5 to fit 5R | 85% | leaves a thin border on one pair of edges |
The two share the 1 : √2 shape but are not one halving apart, so a fit-to-page scale still leaves a small border.
Beyond the Measurements
Envelopes: A5 fits C5, C6; 5R has none.
