One roll short of a feature wall
The customer chose a large pattern paper for the dining room feature wall and the chimney alcoves. The rolls were ordered using the usual count per wall. Halfway through the last alcove, it is clear the pattern repeat has eaten more than expected. One more roll is needed. The supplier has the paper, but not from the same batch, and the new roll is a slightly different shade.
On another job, the delivery had two batch numbers mixed in the box, and nobody checked before hanging.
Why wallpaper orders go wrong
Wallpaper quantities depend on wall height, width, the number of drops from each roll, and the pattern repeat, which can waste a lot on large or half-drop patterns. Rules of thumb work for plain papers and fail for patterned ones. And batch matching is a known risk that is often left to luck.
- Rolls are estimated without allowing for the pattern repeat and match.
- Doors, windows and alcoves are handled roughly.
- Batch numbers are not checked when rolls arrive.
- Spare rolls are not recorded with batch numbers for the customer.
- Orders are placed from a count in a notebook.
What a short roll costs
A missing roll stops the job until a matching batch is found, which may not happen. A mismatched batch can mean stripping and rehanging a whole wall. Specialist papers can be expensive and have long lead times. And customers who bought an expensive paper are unhappy when the result shows a shade change.
Wallpaper also brings a particular kind of pressure: the customer chose it carefully, often from a sample book over several weeks, and is excited to see it up. A delay or a visible shade difference lands harder than a delay on a painted wall, because the paper was the whole point of the job. Getting the quantity and batch right first time protects the moment the customer has been waiting for.
The roll calculator and order check we build
- Walls are measured on the phone with height, width and openings, room by room.
- The roll's width, length and pattern repeat, and whether it is straight or half drop match, are entered from the paper's details.
- The calculator works out drops per roll and rolls needed for each wall, with a spare allowance you set, and shows its working.
- The order is placed with a request for a single batch, and the quantity and code are recorded on the job.
- When the rolls arrive, the painter scans or photographs the labels, and the system checks that the batch numbers match and the count is right before hanging starts.
- Spare rolls are recorded with batch numbers and left with the customer, so repairs later can use the same batch.
| Input | Why it matters |
|---|---|
| Wall height | Drops per roll |
| Wall width and openings | Number of drops |
| Pattern repeat | Waste per drop |
| Match type | Straight or half drop |
| Batch number | Shade consistency |
Paper hanging without the gamble
The order is right for the pattern, including the awkward bits. Batch problems are caught before the first drop goes up, when a swap is still easy. The customer has spare rolls recorded with the batch. And the working is on file if there is ever a question about the quantity ordered.
Is wallpaper catching you out?
- You have run short on a patterned paper.
- You have hung mismatched batches.
- Roll counts are worked out with a rule of thumb.
- Batch numbers are not checked on delivery.
- Customers do not know which batch their spares are from.
