Wallsizer is operated by ILLUSTRO S.R.L., a company registered in Romania, 203c, 547570 Solovastru, Mures, Romania · Trade Register no. J26/75/2016 · CUI/VAT: RO35474147 · hello@wallsizer.com
Wallsizer is a web application that computes wallcovering quantities, layouts and cut sheets from the dimensions and product specifications you enter. All results are estimates based entirely on your input. Wallsizer does not measure your site, does not inspect materials and is not a party to any purchase of wallcoverings or other materials; ordering decisions are yours.
Verifying all measurements and quantities on site before ordering material is an express condition of using the service. This requirement is printed on every export. Wallsizer is a planning tool for professionals, not a substitute for professional judgement on site.
Wallsizer is designed and marketed for professional and business use: wallpaper retailers, interior designers, installers and similar trades. You may subscribe as a business or as an individual, but the service, its pricing and its documentation are addressed primarily to professionals.
Access to the paid service requires an account. On the Solo plan the account is tied to one email address and one named user. On the Team plan the account includes up to three named users, each signing in with their own email address. You may not share, resell, sublicense or provide access to your sign-in to any other person; adding a team member on the Team plan is the supported way to give a colleague access. Each user's sign-in works on their own devices, with up to two devices signed in at the same time; signing in on an additional device automatically signs out the least recently used one. We may suspend accounts showing signs of shared or automated access.
The subscription is billed monthly, in advance, at the price shown at signup. New subscriptions start with a 30-day free trial. A valid payment method is required to start the trial. The free trial is available once per customer. If you subscribe again after a previous trial or subscription, billing starts immediately. If you do not cancel before the trial ends, the subscription starts automatically and your payment method is charged monthly until you cancel. You can cancel at any time from the customer portal, in one click, with effect at the end of the current period.
Prices are shown in US dollars and do not include VAT or sales tax. Where tax applies, it is calculated and shown at checkout, before you confirm, based on your billing country and, for business customers, your VAT ID. For EU business customers with a valid VAT ID, the reverse-charge mechanism applies and no Romanian VAT is added. The total you see on the checkout page before confirming is the total you pay.
If you are a consumer in the EU or UK, you have the right to withdraw from this contract within 14 days of subscribing, without giving any reason. To exercise it, email hello@wallsizer.com with an unambiguous statement (you may use the model form below) before the 14-day period expires.
Because new subscriptions start with a 30-day free trial, the 14-day withdrawal period normally expires before any payment is taken. If you withdraw within the period, your account is closed and you pay nothing. If your subscription starts without a trial (for example, after a previous trial), you may still withdraw within 14 days; you will be refunded less a proportionate amount for the days of service already provided. By starting the subscription you expressly request that the service begins immediately during the withdrawal period.
To: ILLUSTRO S.R.L., hello@wallsizer.com. I hereby give notice that I withdraw from my contract for the Wallsizer subscription. Ordered on [date] · Name [name] · Email used at signup [email] · Date [date].
You can cancel at any time; access continues until the end of the period already paid, and no further payments are taken. We do not refund periods that have already started. This does not affect your statutory rights: if the service does not conform to the contract, you retain all remedies provided by law, including, where applicable, price reduction or reimbursement under Directive (EU) 2019/770 as implemented in your country.
Founding-member pricing, where offered, remains locked for as long as the subscription stays continuously active. If we change regular prices, we will notify you at least 30 days in advance; the new price applies from your next billing period after the notice, and you may cancel before it takes effect.
The Wallsizer application, its interface, source code, calculation engine, drawings, brand and documentation are the exclusive property of ILLUSTRO S.R.L. and are protected by copyright and other laws. Your subscription grants a limited, non-exclusive, non-transferable right to use the service for your business. It grants no ownership.
The dimensions, settings and design images you work with are yours. Projects are stored on your devices and synced to your account so they follow you across devices (see the Privacy Policy for details on how projects and design images are stored). The documents you generate (PDF, JPG) are yours to use with your clients. You are responsible for the accuracy of the dimensions, for any content and branding you include, and for the measurements submitted by persons you invite through a measure link.
We work to keep the service available and accurate, but we do not guarantee uninterrupted availability. We may improve or modify features; if a change materially reduces the service you pay for, you may cancel and, for consumers, exercise any statutory remedies.
Except as expressly stated in these terms and except for rights that cannot be excluded by law, the service is provided without further warranties.
Quantity results are estimates whose accuracy depends entirely on the data you enter: wall dimensions, openings, roll or panel specifications, pattern repeat and match type. Factors outside our control also affect how much material a job actually needs, including manufacturer tolerances and mislabeled product specifications, batch and dye lot variations, printing and trimming differences, substrate and adhesive behavior, installer technique and cutting decisions, and changes made on site. For these reasons an estimate is not a guarantee that a given quantity will complete a given job, and the obligation to verify on site under section 1 applies to every order. This section does not limit the statutory conformity rights of consumers.
To the extent permitted by law, we are not liable for the cost of wallcoverings or any other materials ordered, for reprints or reorders, for differences between batches or dye lots, for installation or labor costs, for site delays, or for loss of profit, revenue, contracts or business opportunity, all of which are indirect or consequential losses arising from ordering decisions that remain yours under sections 1 and 13.
To the extent permitted by law, our total liability for all other claims arising from the service is limited to the amounts you paid in the 12 months before the event giving rise to the claim. Nothing in these terms excludes or limits liability for intent, gross negligence, death or personal injury, or any other liability that cannot be excluded by law. For consumers, mandatory consumer protection rules prevail over this section to the extent of any conflict.
If a third party brings a claim against us because of your use of the service in breach of these terms, the content or branding you add to exports, the documents you provide to your own clients, or measurements submitted through a measure link you sent, you will indemnify us against the resulting damages and reasonable costs, to the extent the claim is attributable to you.
This section does not apply to consumers where such indemnities are restricted by law, and it does not shift to you any liability that section 14 places on us.
Neither party is responsible for delays or failures caused by events beyond its reasonable control, such as outages of power or telecommunications, failures of the third-party providers listed in the Privacy Policy, natural disasters, war, or acts of public authorities. Obligations are suspended for the duration of the event; if it lasts more than 60 days, either party may cancel the affected subscription. Payment obligations for service already provided are not affected.
These terms and the Privacy Policy are the entire agreement between us regarding the service. If a provision proves invalid, the rest remains in force, and the invalid provision is replaced by the valid rule closest to its intent. Not enforcing a provision is not a waiver of it.
You may not assign the subscription without our consent; we may assign it as part of a sale or reorganization of the business, with notice to you. Legal notices travel by email: to you at your account address, to us at hello@wallsizer.com. If you send us ideas or feedback, we may use them to improve the service, without obligation to you.
We may suspend or terminate accounts that materially breach these terms, in particular sections 3 and 10. Where the breach is remediable, we will give notice and a reasonable opportunity to remedy before termination. Amounts already paid for periods affected by a justified termination for breach are not refunded, except where the law requires otherwise.
We may update these terms. For material changes we will notify you by email at least 30 days before they take effect; if you do not agree, you can cancel before the effective date. Continued use after that date constitutes acceptance.
These terms are governed by Romanian law. If you are a consumer, you also benefit from the mandatory consumer protection provisions of the law of the country where you habitually reside, and you may bring proceedings in the courts of that country. Consumers in Romania may address the National Authority for Consumer Protection (ANPC, anpc.ro), including its alternative dispute resolution service (SAL). Consumers in other EU countries may use the alternative dispute resolution bodies designated in their own country.
