How much storage will your event need?

Set your guest count and what you expect per guest. The sliders start at the hard per-file limits Gathmo enforces, so the first number you see is the most it could ever be.

Your event

Guests

Photos per guest

Videos per guest

Voice messages per guest

File sizes

These start at the maximum Gathmo accepts. Drag them down to what you actually expect — the sliders are your estimate, not ours.

Photo: 25 MB

Video: 1536 MB

Voice message: 50 MB

Gathmo rejects any single file above these limits at upload and again at ingest, so nothing larger can reach your album.

What that adds up to

Smallest plan that covers it

Grand — $99

250 GB included, 147.3 GB needed.

Album stays available for 365 days.

The ceiling is a fact, not an estimate

Even if every single upload arrived at the maximum allowed size — 25 MB per photo, 1536 MB per video, 50 MB per voice message — this event could not exceed 147.3 GB. That is enforced, not assumed.

Most storage estimates are guesses. This one has a floor and a lid.

Nobody can tell you how big your guests’ photos will be. What we can tell you is the most they are allowed to be, because Gathmo enforces a size cap per file at upload and checks it again against the stored object. So instead of a made-up average, you get a real upper bound — and you can drag the sliders down to whatever you actually expect.

Questions about event storage

How many photos does a wedding actually produce?

It depends on your guests, and anyone quoting a precise average is guessing. Use the guest count and per-guest fields to model your own event, then check the result against the plan sizes rather than against someone else’s number.

What happens if we go over the storage on our plan?

Uploads stop rather than silently overwriting anything. Moving up a plan raises the limit; the calculator shows the smallest plan that covers what you modelled.

Does the album stay online forever?

No, and that is deliberate. Each plan states a retention period, shown with the recommendation above. Download the originals before it ends and you keep them regardless.

Do videos really need that much room?

They dominate the total once guests send more than a clip or two, which is why the video slider moves in larger steps. If you only expect a handful, set videos per guest to zero and watch the figure drop.
