Removing the distance, when you live apart
If the honest problem is that you never see each other, spend the money on that rather than on an object to post. A train fare beats a parcel.
Against what people spend
The typical amount falls inside this range: $55.65 on average, per Empower (2025), against a range of $50–$160. Spend at the lower end and you are spending what most people spend.
This is the national figure for an adult's birthday gift, not a breakdown for a sister — no published survey we could find breaks spending down by relationship, and the per-relationship numbers you will see elsewhere carry no source.
Name the actual gap
For siblings in different cities the thing missing is usually not possessions. Buying an object and shipping it addresses the birthday; paying for the visit addresses the reason the birthday felt distant.
This is the same money doing more work. A fare, a night in a hotel so nobody sleeps on a sofa, a taxi at an awkward hour — each removes a specific obstacle that has been quietly preventing the visit.
Book it, do not offer it
An open offer to come and visit sometime is not a gift, because the arranging is the obstacle. A booked date is.
Book the boring parts too. Visits fail less on the ticket price than on the childcare, the day off, the dog. Paying for whichever applies is the unglamorous half that actually makes it happen.
If the visit is you going to her
Cover your own costs and say so. A gift that arrives as a houseguest with expectations is a cost to her disguised as a present.
When this is the wrong gift
Not if the distance is deliberate. Families are complicated, and some distance is a choice rather than a logistics problem. A gift that closes it uninvited is not a gift.
Not if she would have to host. Paying your own travel while she absorbs the cooking, the bedding and a week of tidying has moved the expense rather than covered it.
Not a date you picked alone. A booked visit that lands on her worst week is an obligation with your name on it.
