How Much Did I Crop My Photo? 🤔📸 Let’s Do the Math!
As a photographer, I know the struggle when someone asks,
"How much did you crop that photo?" or
"How far away was the subject?" It’s a common question, but when it comes to providing a clear, definitive answer, it can get a bit tricky! 😅

So today, I’m going to break down exactly how to answer that question !🔍✨

Hi there!

Welcome🎉 Karibu🌍 ようこそ!🎏😊 வரவேற்கின்றேன்🙏💖! Bienvenido🎉👋

أهلاً وسهلاً 🌟🤗Willkommen🍻👋 स्वागत है 🌈✨


Let’s start with an example! Here’s a screenshot I grabbed from Lightroom Classic that shows a visual of the crop compared to the original image. 👇

How to Calculate the Crop Percentage

To give a precise answer, you can use this simple formula for your crop percentage:
The Math:

Cropped image: 3619 x 2036

Original image: 9568 x 6376

The crop percentage can be calculated like this:

Crop % = (Exported megapixels ÷ Original megapixels)

Or more specifically:

Crop % = (Width_cropped × Height_cropped) ÷ (Width_original × Height_original) × 100

Let’s break it down:

Cropped megapixels: 3619 × 2036 = 7,373,884 pixels

Original megapixels: 9568 × 6376 = 61,010,688 pixels

Crop percentage = (7,373,884 ÷ 61,010,688) × 100 = 12%

Where Do You Find the Dimensions?

Easy! 👌 To get these numbers, head to the Properties > Details section of your photo file. On a Mac, right click > Get Info > More Info

You’ll find the dimensions from the original (RAW) file and the exported (cropped) version. In my case, for the red-headed woodpecker shot, the cropped image is only 12% of the original size! 🌟

Zoom Reach 📷🔭

Now, let’s talk about zoom. You might have noticed I used a 600mm lens for the original shot. But since the crop is 12% of the original, you can think of it like having an 8x zoom lens, which is roughly equivalent to a 4800mm zoom lens. 😲 That's some serious zoom power!

“My Favorite Game of Guessing!” 🎯

You thought that 4800mm reach is wild, right!

But in reality... you know what else is wildly impressive? My ability to estimate the distance between me and the bird. 😂 According to my very optimistic calculations, the woodpecker was about 100-150 feet away from the boat when I snapped this photo. BUT—and this is the fun part—who really knows? I might’ve been looking through my zoomed-in lens like it was a magic window to a bird kingdom and just forgot how far I was. 😆 100 feet? Maybe. 150 feet? Possibly. 200 feet? Oh... that feels too far, but I’m sticking with it! 😎

Conclusion!

So next time someone asks you how much you cropped, you can give them a precise, math-backed answer. But when it comes to estimating distances... well, you might want to just nod and smile. 🤷‍♂️ I mean, I’ll go ahead and guess 100-150 feet, but take that with a giant pinch of optimism. 😜
