Cloud Storage Planner — How Much Space Do You Need?

A cloud storage planner converts your photo, video, document and backup totals into the plan size you should buy — instead of guessing between the 200 GB and 2 TB tiers.

Quick answer: Add up what you will actually sync: a typical phone library (30,000 HEIC photos ≈ 54 GB) plus videos (200 clips ≈ 120 GB) plus documents (5 GB) is about 180 GB — which fits a 200 GB tier with little room, so a 2 TB plan is the comfortable choice.

Cameras and phones report capacity in binary units while cards and drives are sold in decimal, so a “64 GB” card shows about 59.6 GiB in the device — that 7% is convention, not a fault. Real-world counts land a few percent below the numbers above because of thumbnails, sidecar files and the file system's own metadata.
Counts are a planning estimate: file sizes vary with content, cameras write extra sidecar files, and every filesystem keeps some bookkeeping space. The second row shows a conservative count at 93% usable capacity.

Double-count riskPhotos synced twice (phone + computer folder) consume quota twice

Count what syncs, not what exists

Cloud quota is consumed by files the client uploads, not by files you own. If a photo library syncs from both a phone app and a computer folder, every photo counts twice — a common cause of “I have 200 GB and my library is 150 GB, why is it full?” Audit the synced folders first, then size the plan.

Growth is the deciding factor

A plan that just fits today will be full within a year for most phone users: 12 MP HEIC photos at 1.8 MB plus 4K video at 11 GB per hour add up quickly. A simple projection — current usage plus last year's growth — usually pushes the decision one tier up, from 200 GB to 2 TB, and that gap is where most people end up anyway.

Versioning and trash use real space

Cloud drives keep deleted files in trash for 30 days and retain version history, so quota is consumed by data you cannot see. If you are near a limit, empty trash and check version history settings before assuming the plan is too small.

When to use this calculator

  • Choosing between a 200 GB and 2 TB plan for a phone and laptop.
  • Checking whether a photo library fits a free tier before paying.
  • Planning cloud storage for a small business's documents and backups.
  • Auditing double-synced folders that consume quota twice.
  • Estimating how long the current plan will last.

Frequently asked questions

Frequently Asked Questions

How many photos fit in 200 GB?
About 110,000 phone HEIC photos at 1.8 MB, or 25,000 camera JPEGs at 8 MB — before video.
Is 200 GB enough for photos and videos?
For photos, generally yes. Add video and it depends: 200 clips of 4K footage can be 120 GB on its own.
Do I need 2 TB of cloud storage?
If you back up a laptop, a photo library and phone video, yes — that combination routinely passes 500 GB within a year.
Does cloud storage use my data plan?
Only while syncing; a Wi-Fi-only setting avoids mobile data use, at the cost of delayed backups when away from home.
