Suggested sizes

• 320 × 580. Narrow columns. Tall enough for the airline note and the credit line.
• 360 × 580. A comfortable default.
• 420 × 560. Wider text, so the frame can be a little shorter.

The calculator stays readable down to about 300 pixels wide. It uses a white background so it stays clear on light pages. Search engines should index this page, not the frame.
