How much do you
actually need?

Pop in your room dimensions, the size of your roll, and we'll do the arithmetic. We add a 15% pattern-match buffer by default — you can dial it up for big repeats.

Step 01 · Your Room

Tell us about the space

All four walls? Just one accent? Give us the perimeter (sum of every wall you're covering) and the ceiling height.

This is an estimate, not a quote. Pattern repeats, drop direction, irregular walls, soffits, and seam placement can all change the final yardage. Please confirm with your designer or wallcovering installer before placing an order — and order from a single dye lot.
02 — Why Cover

Paint is fine.
Pattern is personality.

Paint gives a room a mood. Wallcovering gives it a story. Where a coat of latex offers a single flat note, a covering brings rhythm, depth, texture, and the unmistakable feeling that someone chose this room — that it wasn't simply rented to a beige.

Modern wallcoverings have come a long way from the peeling florals you remember from your grandmother's powder room. Today's papers, vinyls, grasscloths, and peel-and-stick films are durable, washable, often removable, and printed in ranges that span every aesthetic from quiet linen-look neutrals to maximalist hand-blocked botanicals. They hide imperfect drywall, dampen sound, add subtle insulation, and — crucially — they last. A well-installed paper can hold up for fifteen years or more, where a painted wall is begging for a touch-up by year three.

01

It hides what paint magnifies

Patterned coverings are wonderfully forgiving with imperfect plaster, drywall seams, and the small dings any wall accumulates over a decade of life.

02

It outlasts a paint job

Quality vinyl and non-woven papers can shrug off scuffs, hand prints, and the occasional toddler. Many are scrubbable; some are even bleach-cleanable.

03

It transforms a room instantly

A single accent wall in a bold print does what gallons of paint can't: gives the room a clear focal point, a sense of intention, and a distinct point of view.

03 — A Field Guide

A short, opinionated
guide to covering walls.

The materials, briefly

Non-woven papers are the modern default — dimensionally stable, paste-the-wall application, removable in a single dry strip. Vinyl coverings are the workhorses of kitchens, baths, and high-traffic hallways: scrubbable, water-tolerant, and forgiving. Grasscloth is woven from natural fibers (sisal, jute, arrowroot) and adds quiet, room-defining texture; it shows seams by design, which is part of its charm. Peel-and-stick has matured into a genuinely good renter-friendly option for short stays and accent walls.

The repeat is the thing

Every patterned covering has a pattern repeat — the vertical distance after which the design starts again. A small repeat (under 6 inches) wastes very little material. A large repeat (24 inches and up) can mean throwing away a foot or more from each strip just to align the design. Repeats also have a match: straight match (each strip identical at the seam) or drop match (every other strip shifts by half the repeat). Always — always — buy a little extra.

Plan for the seams

Wallcovering happens in vertical strips called drops. A skilled installer maps drops before any paste touches the wall: centering a focal pattern over the bed, balancing partial drops on either side of a chimney, hiding the inevitable mismatch behind a door rather than over the sofa. This is the part of the job homeowners undervalue and pros earn their fee on.

Order from one dye lot

Wallcoverings are printed in batches called dye lots or run numbers, and color can drift subtly from one lot to the next. If you need to re-order mid-project because you came up short, the new rolls may not match. The fix is simple: measure carefully, add a buffer, and order everything together. (See: this calculator.)

Drop
A single vertical strip of wallcovering, cut to the height of the wall plus trim allowance.
Bolt
A continuous roll of wallcovering. American bolts are typically two single rolls joined together.
Pattern Repeat
The vertical distance after which the printed design starts over. Bigger repeat = more waste.
Match
How adjacent strips line up. Straight: same horizontal line. Drop: offset by half a repeat.
Sizing
A primer-like coat applied to the wall before installation, helping the covering bond and slide into place.
Dye Lot
A single print run. Always order all your rolls from the same lot to ensure color consistency.
Booking
Folding a pasted strip onto itself to let the paste activate before hanging. Not needed for paste-the-wall papers.
Strippable
A covering you can remove later in dry, full-width strips — without steamers, scoring, or apologies.
