Keep one message at the centre
The personalised LED lightbox heart has a published message limit of up to 32 characters. That is a limit for the heart message, not an offer of custom freestanding letter stock. Choose one idea: a welcome, a wedding greeting or a short anniversary message usually gives you a clearer starting point than a sentence trying to do everything.
Write the exact text in a note before using the planner. Count spaces and punctuation as well as letters. The local planner counts your proposed message and rejects a message longer than 32 characters, but it does not prove that every typed symbol is supported by the equipment.
Approve three things separately
- Meaning: both organisers agree what the message says and who it is for.
- Text: names, spelling, spaces and punctuation are copied exactly.
- Layout: the supplier confirms the supported characters and how the message will appear on the actual heart.
For names with accents, an ampersand, dates or unusual symbols, ask explicitly what can be displayed. Do not remove meaningful characters without the person's approval simply to fit a limit. The final equipment layout may need a shorter version even when the typed count is within the maximum.
Prepare a short fallback
Keep a second, simpler version beside your favourite. For example, a brief wedding greeting may be easier to approve than a long pair of names and a full date. Label the fallback as a proposal, not permission to substitute it automatically.
Download the browser-only brief with the heart selected and keep the final agreed text with your quote. Nothing is sent by the planner, and entering a message does not reserve the heart or confirm its availability. If you change the wording later, obtain a fresh layout confirmation before treating the new version as agreed.
