Your headcount does not tell you how many photos a gallery will need. Three simple assumptions can give you a useful planning range. The numbers below are worked examples, not measured participation rates or promises.

Start with contributors, then their selection

Take the number of guests, estimate the proportion likely to contribute their own photos, and estimate how many selected pictures each contributor might send. Multiply: guests × assumed participating share × photos per contributor. Add your own photos and some spare capacity afterwards.

Couples may contribute together, some people prefer not to take pictures, and others share plenty. There is no universal participation rate in this calculation. Think about your group rather than treating every attendee, including children without a device, as a separate uploader.

Three examples you can adjust

50 guests: Assume half contribute four photos each. That is 25 × 4 = 100 photos. Adding 25 places for extra pictures or spare capacity gives a planning total of 125.
100 guests: With the same assumptions, 50 × 4 = 200 photos. Adding 50 places gives 250.
200 guests: One hundred contributors sending four photos each produce 400 photos. Adding 100 places gives 500.

The examples add one quarter of the estimated volume to make the comparison consistent. That is a chosen planning allowance, not a guaranteed safety margin. For a multi-day celebration or particularly enthusiastic photographers, work through a larger scenario too.

Try a busier scenario

Change four photos to eight in the 100-guest example. You now have 400 photos before your own contributions or spare capacity. A plan that fits the first example may not fit this one. Compare both a modest collection and a busy collection rather than relying on one exact forecast.

Include video in your thinking. Where a plan counts photos and videos together, both use the same media allowance. File size and accepted formats may also matter. Use the current package details for actual features and limits; the examples are not automatic package recommendations.

A larger guest list also needs clearer organisation

You may be able to explain the process personally at a small gathering. With many tables, put clear reminders in several useful places. Use the same intended guest link throughout, rather than accidentally dividing the collection between several galleries.

One person checks the printed QR cards before guests arrive.
A second person understands the guest workflow and can offer help.
The DJ or host has a short, optional invitation to contribute.
If reception is poor, guests can keep their selected photos and upload later through the link. Do not promise offline uploading.

Your fill-in planning sheet

Guests: ___ × assumed participating share: ___ × photos each: ___ = ___ contributions. Add ___ of your own photos and ___ spare places. Planned video clips: ___. Our busier scenario totals ___ media items.

Also write down who will keep an eye on the collection and when you will save the files after the wedding. Review the plan shortly before the event to allow for test photos and new requests. Extra capacity can give you room to adapt, but it does not replace a clear plan.

Choose by your scenarios, not a headcount label

There is no rule that 200 guests always need the largest plan. Compare your likely range, video needs and desired availability instead. Foreverpix Free, with up to 50 photos, can help you learn the guest process; 50 photos does not mean a limit of 50 guests. Put the final guest QR code into your print design only once you have checked the destination.
