Parcel Sizes & Limits (At a Glance)

InPost uses simple size bands (Small/Medium/Large or A/B/C, depending on location). Choose the tier that fits your packed item. Tip: select the smallest size that closes comfortably—it’s usually the cheapest and avoids locker rejections.

Packing Tips for Lockers

Use a sturdy box; avoid bulges that can block the locker door.
Seal with strong tape on all seams.
Attach the label on the largest, flattest side and keep barcodes clear.
Add a small second label inside the box with the destination details.

Delivery Times

Typical delivery windows vary by route. The calculator shows the current estimate for your exact collection/drop-off point and destination, plus the latest cut-off times for same-day drop-off.
