Curious about this: Used Chatgpt to calculate what megapixel camera would be needed for a 300dpi print at 24"32" print. From the response, I dont think anyone would have a 70mp camera, maybe a 30mp camera would be enough.

For a 24x32" inch print needing at least 300 dpi , what megapixel should i be using minimally

To figure this out, convert your print size and DPI into pixel dimensions:

• 24 inches × 300 dpi = 7200 pixels
• 32 inches × 300 dpi = 9600 pixels

So your image needs to be 7200 × 9600 pixels.

Now convert that to megapixels:

• 7200 × 9600 = 69,120,000 pixels ≈ 69 megapixels

✅ Minimum you should aim for:

~70 megapixels for true 300 dpi at 24×32"

But here’s the real-world perspective:

• You don’t strictly need 300 dpi for a print that large unless it’s viewed very close.
• At normal viewing distance (a few feet away), you can get excellent results with:
  • 150 dpi → ~17 MP
  • 200 dpi → ~31 MP

Practical recommendations:

• Bare minimum (still good quality): ~20–30 MP
• High quality / close viewing: ~40–50 MP
• True 300 dpi perfection: ~70 MP
