How to use the Golden Ratio Calculator
- 1. Enter a valueA width, height or length in any unit.
- 2. Say what it isThe total, the longer part or the shorter part.
- 3. Use the partsApply them to columns, image crops or type sizes.
Worked example
Split a 960 px layout by the golden ratio and you get 593.31 + 366.69: a main column of 593.31 px and a sidebar of 366.69 px. The longer part is the total divided by φ (960 ÷ 1.6180 = 593.31), and the shorter part is what remains. The special property is that 593.31 ÷ 366.69 and 960 ÷ 593.31 both equal φ, so the whole relates to the big part as the big part relates to the small one. The longer part is always about 61.8% of the total.
The rows add a golden rectangle (960 × 593.31) and sequences that divide or multiply by φ, useful as a set of sizes.
Where it helps, and where it does not
- Layouts: a 62/38 split between content and sidebar feels balanced.
- Type: φ as a type scale ratio gives bold, dramatic headings.
- Crops: placing a subject at about 38% or 62% across an image is similar to the rule of thirds.
Claims that famous buildings, paintings or logos were designed on the golden ratio are often overstated, and good design does not need it. Treat φ as one useful proportion among others, such as 1:2 or the thirds grid. φ = (1 + √5) ÷ 2 ≈ 1.6180339887 is used at full precision in the maths. For other proportions, use the aspect ratio calculator; for golden-ratio type sizes, choose 1.618 in the type scale generator.
Frequently asked questions
Is the golden ratio the same as the Fibonacci sequence?
They are linked: dividing each Fibonacci number by the one before gets closer and closer to φ, for example 89 ÷ 55 ≈ 1.618.
Can I use it for print sizes?
Yes, any unit works. Enter centimetres or inches and set the unit label.
Is the Golden Ratio Calculator free?
Yes, the Golden Ratio Calculator is free. The first time you see your first result, you are asked for your name and WhatsApp number once. After that, this and every other Uncodemy tool opens straight away without the form.
