Display Measurements in — 16S+, 32ND, Decimal options

2.2.7   display

TODO — write this page.

```html

This setting controls the precision and format used to display span measurements on spec sheets and throughout the app. Where page 2.2.3 governs whether measurements appear as fractions or decimals globally, this setting goes one level deeper — specifying exactly how fine the fractional or decimal expression of a span value will be. The three options are 16ths+, 32nds, and Decimal.

Note: This setting applies specifically to span measurements (finger to finger, and finger to thumb). Other measurements such as bridge width, oval dimensions, and hole sizes may follow their own display rules set elsewhere in Settings.

📏 Understanding the Three Options

16ths+ (Sixteenths and halves)

Spans are expressed as whole fractions to the nearest sixteenth of an inch, with half-sixteenth values used where the measurement falls between two sixteenth boundaries (e.g. 4 ⁵⁄₁₆", 4 ¹¹⁄₃₂" where the half-sixteenth is needed). This is the traditional standard used on handwritten and legacy printed spec sheets across most US pro shops. Experienced drillers trained on paper sheets will find this format immediately familiar.

32nds (Thirty-seconds)

Spans are expressed consistently to the nearest thirty-second of an inch (e.g. 4 ¹⁰⁄₃₂"). This provides finer resolution than 16ths+ and eliminates the mixed-denominator appearance of the 16ths+ format — every value uses the same denominator. Useful for shops that measure and record spans to thirty-second precision on their drill press or fitting equipment.

Decimal

Spans are expressed as a decimal number to two or more places (e.g. 4.3125"). No fractions are used. This format is preferred by many Canadian and international shops, and by fitters who enter measurements directly from a digital caliper or digital span gauge that outputs decimal values.

⚙️ Changing the Span Display Format

  1. Open Spectre Cloud at cloud.spectrebowling.com and log in.
  2. Click your pro shop name in the top-right corner to open the Profile menu.
  3. Select Settings from the dropdown.
  4. Navigate to the Display Preferences section.
  5. Locate the Span Measurement Display field and select 16ths+, 32nds, or Decimal.
  6. Click Save. The change takes effect immediately across all spec sheets.

🎳 Which Format Should You Use?

Situation Recommended Format Reason
US shop — experienced drillers, legacy paper sheets 16ths+ Matches the format most US fitters have read for decades
Precision fitting, competitive bowlers 32nds Finer resolution, consistent denominator, easier to compare values
Canada or international shop Decimal Standard outside the US; aligns with digital measuring tools
Shop using digital calipers or span gauges Decimal No conversion needed — enter and read the same format your tool outputs
New shop, no established convention 32nds Consistent denominator is easier to learn and less confusing for new staff than mixed 16ths+

🔄 Relationship to the Global Measurement Format Setting

This setting works alongside — not instead of — the global Decimal vs. Fractional display preference set in page 2.2.3:

  • If your global format is set to Fractional, this setting determines whether spans appear in 16ths+ or 32nds. Selecting Decimal here overrides the global fractional setting for span fields only.
  • If your global format is already set to Decimal, this setting has no additional effect on spans — they will already display in decimal form.
  • ❌ There is no per-sheet override for this setting — it applies shop-wide to all span display.

Tip: Switching this setting at any time is non-destructive — the underlying span values stored in Spectre Cloud do not change. Only the on-screen and printed representation changes, so you can switch formats freely without affecting your data.
