How to Train Your Brain for RTL Thinking (for Design and Accessibility)

Designing for right-to-left (RTL) languages can feel disorienting if you’ve always worked in left-to-right (LTR) environments. The shift is not just a technical difference, it’s a cognitive adjustment. For designers used to Western conventions, designing for an RTL interface is like suddenly writing with your non-dominant hand; it feels confusing, awkward, and counterintuitive. My own early exposure to Arabic and Persian helped me build my RTL muscles from a young age, but most designers encounter RTL much later and find it to be a challenging mental adjustment.

Why Bidirectionality Feels So Hard

If you’re accustomed to LTR, your mind has built long established instincts like scanning from left to right. Because of this, your attention also anchors to the left, so mirroring elements can feel unnatural at first. In RTL layouts, the starting anchor is on the right, with everything on the interface beginning on the opposite side. The sensation of “this looks backwards” is your LTR mental model clashing with this new orientation. Just like learning to train with your non-dominant hand, it feels unnatural at first, but as you continue to build the muscle, it can start to feel more instinctive and less jarring.

Start With the Flow, Not Just Mirroring

A common mistake is to treat RTL as a perfect mirror of LTR. Although the majority of elements are mirrored, there are exceptions to this that must be considered in order for the interface to feel intuitive for a native speaker. For example, navigation order must be flipped, headings are aligned to the right, content begins on the right and moves leftward, drawers and menus open on the opposite side, etc. Rather than simply mirroring an interface horizontally like a photograph, designing for RTL means starting with logical flow, not just by flipping everything.

Ask yourself: Where does the anchor begin in RTL, and where should it naturally move as the user progresses?

That answer anchors everything. For practical guidance and helpful visual examples, see the following links:

What to Mirror — and What Not To

Mirroring in RTL is not absolute. A helpful way to approach it is to think of it as selective mirroring. While overall layout should flip, certain universal or culturally neutral elements should remain as they are. Being intentional about what you flip helps avoid interfaces feeling “off” or uncanny to a native RTL speaker.

✅ Mirror:

• Menus
• Navigation bars
• Spacing
• Directional icons

❌ Do NOT mirror:

• Numbers
• Code snippets
• Media controls
• Brand elements
• Mixed RTL/LTR text

Also note that every region and product has its own nuance. It’s important to research how users in your target markets actually read, scan, and interact with your interface. Further investigation might be required in order to ensure their specific needs and expectations are met. Feel free to expand upon the aforementioned list.

Build Mental Landmarks for RTL

Just like LTR has its familiar cues, RTL needs its own mental “anchors:”

• Primary nav starts on the right and moves left sequentially.
• Headings and key actions anchor right.
• Content flows leftward from a right-side starting point

Accessibility in RTL Design

When you mirror layouts, you’re not only changing visual alignment, you’re also changing how people navigate with assistive technology.

• Screen Readers: Mirrored layouts shift focus order and reading patterns. The starting anchor becomes the rightmost element, so tab and arrow navigation must follow RTL reading flow.
• Keyboard Navigation: Sequential tabbing and arrow key movement should progress from right to left, matching natural reading and interaction order.
• Mixed Content: Not everything in a RTL interface is RTL. Numbers, acronyms, phone numbers, code snippets, brand names. See the WCAG Language of Parts for more on this.

The more you practice new flow patterns, understand what should (and shouldn’t) mirror, and build new mental anchors, the more intuitive RTL becomes. It expands your design empathy, sharpens your flexibility, and helps you build products that truly welcome everyone.
