Google Fonts with slnt/ital Axes

This document analyzes variable fonts in Google Fonts that support slant or italic functionality through variable font axes.

Overview

Variable fonts can implement italic/slant functionality in two ways:

1. Discrete italic variants - Separate font files for regular and italic styles
2. Continuous slant axes - Using slnt (slant) or ital (italic) axes for dynamic slanting

Analysis Results

Total fonts with slant/italic axes: 15

All fonts use the slnt (slant) axis - no fonts use the ital axis.

Command

jq -r '.items[] | select(has("axes")) | select(.axes[] | .tag == "slnt" or .tag == "ital") | .family as $family | .axes as $axes | .variants as $variants | ($axes | map(.tag) | contains(["slnt"])) as $has_slnt | ($axes | map(.tag) | contains(["ital"])) as $has_ital | ($variants | contains(["italic"])) as $has_italic_variant | [$family, (if $has_slnt then "yes" else "no" end), (if $has_ital then "yes" else "no" end), (if $has_italic_variant then "yes" else "no" end)] | @csv' webfonts-vf.json

Key Findings

• All 15 fonts use the slnt axis for slant control
• No fonts use the ital axis (binary italic on/off)
• All fonts have only ["regular"] variants - no separate italic font files
• Slant ranges vary from -15° to +14° depending on the font
• Bitcount family has 6 variants, all with the same slant range (-8° to 0°)

Slant Ranges

Font	Slant Range
Afacad Flux	-14° to 14°
Bitcount family (6 fonts)	-8° to 0°
Cairo, Cairo Play	-11° to 11°
Commissioner, Geologica	-12° to 0°
Gluten	-13° to 13°
Recursive	-15° to 0°
Roboto Flex	-10° to 0°
TikTok Sans	-6° to 0°

Design Implications

Fonts with slnt axes provide:

• Continuous slant control - users can adjust the exact degree of slanting
• Single font file - more efficient than separate regular/italic files
• Flexible styling - can create subtle or dramatic slanting effects
• No separate italic variants needed - slanting is handled dynamically

This approach is particularly useful for:

• Design systems requiring precise control over text styling
• Applications where file size optimization is important
• Creative typography where custom slant angles are desired
