Passers-by give a window two or three seconds. One clear message, prices they can read and opening hours on the door turn a glance into a step inside.

A shop window works best with one main message in large lettering readable from across the street, A3 sale or offer signs at eye level, price tickets of A6 or smaller beside the goods, and an A5 opening hours sign on the door. Print on 250 to 300 gsm card, fix it with removable tape and change the window monthly.

New season, summer sale, gifts for Father's Day: one idea in large letters. A window with five messages is read as none.
What is reduced and by how much, such as up to 50% off selected knitwear, at eye level. Be specific; vague sale signs attract fewer people inside.
A small ticket beside each item on display. Many people will not come in to ask, and a visible price answers the question that keeps them outside.
Every day of the week, with the hours and any lunch closing, plus a phone number or website. Shoppers checking at 6 pm on a Sunday decide whether to come back.
A few large letters or shapes for the season or a local event, fixed to the glass or hung on fishing line. They signal that the window changes and is worth looking at again.

| Sale sign | A3 (29.7 × 42 cm) | Seen from the pavement and passing cars |

| Price tickets | A7 to A6 (7.4 × 10.5 to 10.5 × 14.8 cm) | Visible without hiding the goods |
| Opening hours sign | A5 (14.8 × 21 cm) | Fits a door panel at eye height |

For a message read from across a high street, letters around 15 cm tall or more are a sensible starting point. Test it by printing one letter, taping it up and reading it from the opposite pavement.
Many independent shops change the window every two to four weeks, and always for the season or a local event. Even small changes, such as a new main item, tell regular passers-by something is new.
In the UK, price and sale claims must not mislead customers, for example about the previous price or how much is reduced. Check current trading standards guidance before running a sale.
No. Leave clear glass so people can see in and the shop looks open and welcoming. Some insurers and landlords also have views on blocked windows, so check your lease and policy.
