A truly life-size banana on your screen
Hold a bank card upright against the screen, then slide until the outline matches its edges.
Hold any bank card, ID card or loyalty card flat against the screen. Drag the slider until the dashed outline matches the card's edges exactly. These cards are all the ISO ID-1 size, 85.60 × 53.98 mm, so this sets the true scale.
Type your screen's diagonal size in inches instead. It's close, but less exact than a card.
Enter a size between 3 and 120 inches, for example 13.3 or 27.
On a cold evening in October, I had urgent need for a banana for scale. Alas! No banana was at hand. And thus germinated the idea for Banana for Scale. Now everyone has access to an accurate banana for any and all measurement needs. Any time. Any place.
Built for the bestest of gibbons, Daniel.
Banana for Scale is free, with no ads and no tracking. If it saved you a trip to the fruit bowl, you can buy me a banana.
