SIZING SHEET GUIDE
Below we focus on the steps to build out a sizing sheet within FireWriter. For more generalized instructions on using the system, visit our FireWriter Distributor User Guide.
OVERVIEW
- You will need to download the sizing form from the quote in which those sizes will be submitted. Ensuring you download the correct/current sheet will prevent submission errors.
- Spreadsheets will populate the data into the integrated form fields and are not saved as attachments once the information is uploaded. You may want to keep a copy for your records.
- Do not save sizing templates to your personal device as they may become outdated.
- For suspenders, a dash is required for the range of sizes you want. For example, use 28-32 instead of 2832.
FORM FEATURES
- This applies to both the "Name" and "Name/Rank/ID" columns on the sizing sheet as well as the "patches" section within your quote
- Any text, such as the word “blank”, "N/A" or other characters, should not be used
All measurements and required fields must be completed for the system to accept the sizing sheet.
Likewise, all required fields within the quote must be completed before submitting an order. The system will flag and notify you of any missing information.
Hip measurements are required for all FireWriter quotes for AeroFlex and FXR product lines.

VIRTUAL SIZER
The Virtual Sizer harnesses the power of AI to revolutionize sizing recommendations, using just a few quick measurements. These measurements can be conveniently sent to firefighters for completion via email or handled right at the station.
While completely optional, this cutting-edge technology has been rigorously tested and proven to deliver exceptional accuracy. Even better, the system gets smarter and more precise over time as additional data is added.
At Fire-Dex, we fully stand behind this innovation. In the rare case of a mis-sizing, we’ll make it right—guaranteed.
Measurements can be completed either virtually or in person.
For virtual completion, you have two options:
- Upload a file – Download the sizing template, add the email addresses of the firefighters, and reupload the completed sheet into the system.
- Manual entry – Enter email addresses directly into the sizing sheet.
For both methods, click "Send Invite" once all emails are entered.
To complete measurements in person, click "View Virtual Sizer" and follow the on-screen instructions.
