Plancher dans le garage

Bonjour,


Je souhaiterai profiter de la hauteur de mon garage pour réaliser un plancher afin de stocker du matériel encombrant mais pas très lourd (transat, carton vêtement...)
Mon garage fait 4 m de large, je compte fixer des solives le long de 2 mur afin d'y fixer des sabots.
ces sabots permettront de soutenir d'autres solives qui constitueront la base du plancher.
dans un premier temps, il n'y aura très certainement pas de plancher a proprement parlé. Il n'y aura que les "poutres".
Je précise qu'il n'est pas du tout envisagé de marcher sur cette structure.
voici un schéma pour compléter le tout.

voici mes questions:
- Quelles dimensions prendre pour les solives qui serviront à fixer les sabots?

merci pour vos conseils et réponses.
