💾 Storage Space Calculator
Never run out of card halfway through a shoot. Enter a photo count and average file size — with optional video — to see the total storage in GB, or flip it around to see how many photos a card or drive holds.

What is a Storage Space Calculator?
It sizes your storage before you shoot. Tell it how many photos you expect and their average file size — add clips of video if you're recording — and it totals the gigabytes you'll fill; ask the other way and it tells you how many frames a given card or drive can hold.
Use it to buy the right memory card for a wedding or trip, to plan backup drive capacity for a growing library, or to decide between RAW and JPEG when space is tight.
❓ Frequently Asked Questions
How much storage does a photo shoot need?
Multiply the number of shots by the average file size, then add any video. A thousand 25 MB RAW files come to about 24.4 GB; add a half-hour of 4K video at roughly 350 MB per minute and you'll want closer to 35 GB. This tool sums photos and video for you so you can pick the right card before the shoot.
How big are RAW and JPEG files?
It varies by camera and content, but as a rough guide: JPEGs from a 24 MP camera run 6–12 MB, uncompressed RAW files from the same sensor run 25–50 MB, and high-resolution 45–60 MP RAWs can exceed 80 MB each. Video is far heavier — 4K can consume 300–400 MB per minute. Always estimate on the generous side.
How many photos fit on a 64 GB card?
Divide the card capacity by your average file size. A 64 GB card holds about 2,621 photos at 25 MB each, or over 5,000 at 12 MB. Switch this calculator to 'storage → photos' mode to get the number for your own file sizes and card capacities instantly.
Why does a 64 GB card hold less than 64 GB?
Two reasons. First, manufacturers often label cards in decimal gigabytes (1 GB = 1,000,000,000 bytes) while devices count in binary (1 GB = 1024 MB), so the usable figure is smaller. Second, the file system reserves a little space. This calculator uses the binary 1 GB = 1024 MB convention to match how your camera reports free space.
